Question

The length and breadth of a rectangular field are in the ratio 8:3. If the perimeter of the field is 99 m

, find the length of the field.

Answer 1

36 m

Explanation:

Perimeter = 2L + 2w = 99

2(L + w) = 99

L = length = 8x

w = width = 3x

2(8x + 3x) = 99

16x + 6x = 99

22x = 99

x = 99/22 = 4.5

L = 8x = 8(4.5) = 36
