Question

Que13. The length and the breadth of a rectangular park is in the ratio
5:3 and its perimeter is 120m, find the area of the park.​

Answer 1

Step-by-step explanation:

ratio of length and breadth = 5:3

let length = 5x

and breadth = 3x

perimeter of rectangle = 2(l+b)

120 = 2(5x + 3x)

(5x + 3x) = 120/2

8x = 60

x = 60/8

x =7.5

length = 5x = 5 x 7.5 = 37.5 m

breadth = 3x = 3 x 7.5 = 22.5m

area of the rectangular park = lxb = 37.5m x 22.5 m

= 843.75 sq. m.
