Question

The length and breadth of a rectangular park are in ratio 5:2. If its perimeter is 168m, find its length and breadth​

Answer 1

Answer:

length = 60 m

breadth = 24m

Step-by-step explanation:

length = 5x

breadth = 2x

perimeter of rectangular park =2(l+b)

168m = 2(5x+2x)

168 m = 2( 7x)

168 m= 14x

168/14 = x

12= x

length = 5x = 5×12 = 60m

breadth = 2x = 2×12 = 24m

Answer 2

let length and breadth be 5x and 2x respectively.

Perimeter = 2(l+b)

168 m = 2(5x+2x)

168 m = 2(7x)

168 m = 14x

x = 168m/14

x = 12 m

Put the values of x,

length = 5x = 5×12 = 60m

breadth = 2x = 2×12 = 24m

Hence, the length and the breadth of a rectangular park is 60m and 24m.

Hope it will help you:)!✌️
