Question

The length of a rectangle is 5/4th of its width. If the perimeter of the rectangle is 81 then find the area of the rectangle?​

Answer 1

Step-by-step explanation:

Let the length of the rectangle be l meter and the breadth be b meter.

A/Q ➡ l=5/4b

Perimeter of rectangle= 2(l+b)

➡81=2(5/4b + b)

➡71 = 9/2 b

➡b = 71× 2/9=142/9 =15.7meter

Therefore, the breadth of the rectangle is 15.7 meter and the length is 19.675 meter.
