How can i find the perimeter of a rectangle with one side length and the area?
divide the area by the length of the side you know. This will give you the length of the other sides. Then you can add the lengths of all 4 sides to find the perimeter. Is the area really 60,000 m squared or is it 60,000 cm squared? If it really is 60,000 m squared, you will need to change 400 cm to 4m before you divide. That would make the other side 15,000m. So I am guessing that it should be 60,000 cm squared.
The perimeter of a rectangle is 34cm. one side is 11cm longer than the other side.?
Perimeter = 34 cm side a= 11+x side b= x Now we can formulate a equation to solve this 34 = 2(11+x) + 2(x) We multiply the side a and b, by two, because we have two sides of each, to make 4 sides in total 34 = 2(11+x) + 2(x) 34 = 2(11)+2x + 2x 34= 22 + 4x 34-22=4x 12=4x x= 12/4 x= 3 Now that we have the value of x=3, we can find the length of the two longer side x+11= long side 3+11= 14 The lengths of the sides are: two sides of 14cms and two sides of 3 cms To verify this 14cm + 14cm + 3cm + 3 cm = 34cms Hope I helped you
The perimeter of a square is 4o inches. Find the length of its diagonals?
A square has 4 equal sides, so divide 40 by 4 to find that each side length is 10 in. A square also has 4 90-degree angles, also called right angles. If you draw in a diagonal, you'll see a right triangle. Since both "legs" of the triangle - the 2 sides that are part of the square - have equal lengths (10 in.), the angles they make with the diagonal are equal. Every triangle has 180 degrees. (180 - 90)/2 gives you the measure of each of those angles. Now you know it's a special 45-45-90 triangle, and you know the legs are 10 in. Now there are two ways you can proceed to find the length of the diagonal. The fastest is to use special right triangles. It is a proven fact that the ratio of a leg of a 45-45-90 triangle to its hypotenuse (long side) is 1 : square root of 2. So 1/(square root 2) = 10/x. x = 10 times the square root of 2. That's your answer. Or you can use trig ratios, in which case sin(45) = 10/x x = 10/sin(45) x = 10 times square root of 2

Help please...The perimeter of a square is 56 feet. The side length is 4x feet. What is the value of x?
A square has four equal sides. The perimeter is equal to the length of all sides. If one side is 4x, the perimeter is 16x. 16x = 56 x = 56/16 = 7/2 = 3.5
When the perimeter of the figure is given, how do you find the length of the indicated side?
You'll need more information than just the perimeter. You can't find the length of one side from just the perimeter. You need to know the area, or the fact that the figure is a square, or some other relevant data.
A square has a perimeter of 36 inches. What is the area?
1. If the square has a perimeter of 36 inches, you know each side is 9 inches (36 divided by 4). You multiply the length and width (9 times 9) to get 81 square inches. 2. Perimeter is the sum of all the sides. Rectangles have pairs of sides that are the same length and width, so just subtract 2 (7 cm) from 35, and divide that by 2. (35 -2(7)=35-14=21), 21/2 =10.5 cm. 3. Use the Pythagorean Theorem to solve this one. The diagonal makes the square into two big triangles, with each diagonal stretching all the way across the square. The diagonal is the hypotenuse (c squared). The other sides are "a" and "b". You know they are the same length since it is the side of a square, and a squared plus b squared equals c squared. c squared =7 squared=49. Both a squared and b squared equals 24.5. Take off the square roots, and you get that both a squared and b squared equal square root 24.5. Multiply those two values together, and the area of the square is 24.5 feet squared. Sorry if this is a little confusing. I didn't know how else to explain it.
The perimeter of a square is not more than 80cm. What is the largest possible area of the square?
The answer, as you pointed out, is 400 sq cm. Here is how I did this problem If I want a larger square the side length would have to be longer. To get the longest side length I need to use the longest perimeter I can get. Since the largest possible perimeter is 80 cm long the perimeter that I will use is 80 cm. 1). there are 4 congruent sides in a square. to find the one side length I need to divide the length of the perimeter by 4. 80/4=20cm the length of one side is 20cm 2). Now that I know the side length I can eazily find the square's area by using the formula Area=base(height). Because the square has congruent sides I would use 20 for both base and height. A=b(h) plug it in A=20(20) A=400 sq cm Have Fun :)
The perimeter of a square is 30 inches. Its area is?
Well first you need to find the length of one side. Since squares are all equal in side length, you can divide the total perimeter by four because a square has four sides. 30/4= 7.5 Each side length is 7.5 inches. To find the area multiply two of the sides together since the width is the same as the length (so it doesn't matter which two sides you choose). 7.5 x 7.5= 56.25 The correct answer is D.
Isosceles triangle perimeter? help. :(?
Ok, so in an isosceles triangle the perimeter=length of the sides. Also, two sides are the same length. Now, the problem tells us that one side length is four less than the length of one of the two congruent sides. Let's call this first side length x. Thus, if x is four less than the other two sides, then those sides must each have a length of x+4. Perimeter=(x)+(x+4)+(x+4). This can be simplified into Perimeter=3x+8. Now, we'll substitute in the actual perimeter, which is 32. The equation reads: 32=3x+8 Subtract 8 from each side so that the equation now reads 24=3x Now, divide both sides by 3 to get that x=8. To find the side lengths, we must go back to what we said in the beginning. Remember that one side was simply x, meaning its length is 8. Then, we said that the other two sides were x+4. We add 8 to four and get that each of these sides has a length of 12. Therefore, the three sides are 8, 12, and 12. :))
