Question

width of the rectangle is two thirds of its length if the perimeter is 180m
find the dimension of rectangle

Answer 1

Let length be x. Therefore width = 2/3x (i.e) y=2/3x

We know perimeter= 2(l+b)

Here, perimeter=180m

Therefore, 2(x+2/3x) = 180

x + 2/3x = 180/2

3x+2x/3=90

5x=90*3

x=270/5

Therefore x=54 (i.e) length =54m and breath=2/3x=2/3×54=2×16=32m
