What is the length and breadth of a rectangle with a perimeter 48, and the length is 3 times its breadth?
Question: What is the length and breadth of a rectangle with a perimeter 48, and the length is 3 times its breadth?The perimeter of a rectangle is the sum of the lengths of its sides.[math]P = L + W + L + W = 2L + 2W = 48[/math]Therefor, [math]L + W = 24[/math]From the given information [math]L = 3W[/math]Using substitution: [math]3W + W = 24[/math][math]4W = 24[/math][math]W = 6[/math][math]L = 3(6) = 18[/math]Therefor, the dimension of the rectangle are 18 by 6.
If the rectangle is 45 cm and its length is 9 cm, then what is the width?
The given question is as follows:-(1). If the perimeter of a rectangle is 45 cm and its length is 9 cm , then what isthe width ?Solution:- we know that(length+breadth) = perimeter of rectangle / 2.or. 9 cm + breadth =45 cm/2or. breadth = 22.5 cm - 9 cmor breadth = 13.5 cm. Answer.(Here breadth of a rectangle is greater than its length.)******************************OR******************************(2) If the area of a rectangle is 45 cm^2 and its length is 9 cm, then what is thewidth ?Solution:- we know thatBreadth of a rectangle= area of a rectangle/ length of rectangle.= 45 cm^2/9 cm= 5 cm. Answer.
The ratio of the length of a rectangle to its width is 4:3. Its area is 300 square inches. What are its length and width?
Let the length is 4 x and breadth is 3 x4 x * 3 x=300 square inches12x^2 =300x^2 =25x =5 inchesLength = 4*5=20breadth=3*5=15 inches
The length and breadth of rectangle are in the ratio of 13:7. If the area of a rectangle is 2275 cm squared, how do you find the length and breadth?
13 x 7 = 91, so that is the area of our “unit rectangle”2275 / 91 = 25 so we can fit 25 of these rectangles (stacked five high and five across) inside the big rectangle.so if we multiply our “unit” dimensions by 5, we’re about done.7 x 5 = 3513 x 5 = 65and… Voila! 35 x 65 = 2275, so our rectangle is 35cm x 63cm.
A water tank has the following dimensions: length = 1 meter, width = 80 cm, height = 120 cm. How many liters of water can it store?
Volume=length * width * heightLength=1mWidth=80 cm =0.8 mHeight=120 cm = 1.2mSo volume=[math]1*0.8*1.2[/math]=0.96 [math]m^3[/math]Now 1 [math]m^3[/math] = 1000 literSo 0.96 [math]m^3[/math]= 960 liter
If both the length and breadth of the rectangle is increased by 15%, by what percent does the area of the rectangle increase?
Lets assume, for the rectangle, the length is ‘x’ and breadth is ‘y’ So the original area would be x multiplied by y which forms the equation :x*y =xyNow if increase both length and breadth by by 15% each the new equation would be:(x + (15/100)x) * (y + (15/100)y) = (115x/100) * (115y/100) = (23x/20) * (23y/20) = (529/400)xyand 529/400 = 1.3225 which means the area increased by 1.3225 times or by 32.25 %.
The diagonal of a rectangle 18ft long and 15ft 6 wide?
The length of the rectangle = 18ft The width of the rectangle is = 15ft 6inches = 15.5 ft Using the Pythagorean theorem, The diagonal will be equal to = √(length^2 + width^2) = √(18^2+15.5^2) = √(324+240.25) = √564.25 = 23.7539 ft = 23ft 9 inch
What is the area of a rectangle measuring 2/3m by 2/5m?
Recall that the area of the rectangle is A = lw. Given that l = 2/3 m and w = 2/5 m... A = 2/3 m * 2/5 m = 4/15 m² I hope this helps!
21 inches equals how many millimeters?
If you look at google, the first answer to inch/millimeter convertion is: http://manuelsweb.com/in_cm.htm and they give 21 inches equal to 53.3 cms which is 533mm, but your first answer was even more exact I expect which quoted 533.4mm This help stuff can be addictive! Just imagine you get addicted to helping people!
