Question

the breadth of a rectangular garden is one third of its length if the perimeter of the garden is 160m find it's length and breadth

​

Answer 1

Answer:

let the length be x. metre

breadth=1/3x metre

perimeter = 2×(L+B)

160m=2×(x+1/3x)

160m=2× 4/3x

160m=8/3x

160×3=8x

x=160×3

8

x=20×3=60

therefore, length=x=60m

therefore, length=x=60mand breadth=1/3x=20m ANS.
