the ratio of the length of a school ground to its width is 5 ratio 2 find its length is the width is 40 m

Answer 1

ratio = 5:2
width = 40
length = ?
let the width be = 2x
then, the length be =5x
but the width = 40m
= 2x = 40 = x = 40/2 = 20
length = 5*20=100

Answer 2

Ratio = 5:2

Length of the school ground

= 5 × 40

2

= 100m (Ans)
