Question

9. The length and the breadth of a rectangular park are in the ratio 5 :3 and its perimeter ls
128 m. Find the area of the park.​

Answer 1

Answer:

let the length be 5x and breadth be 3x

perimeter = 128m

2(l+b) = 128

2(5x+3x) = 128

2×8x = 128

8x = 128/2 = 64

x = 64/8

= 8

Therefore,

length = 5x

= 5×8 = 40

breadth = 3x

= 3×8 = 24

Area = length × breadth

= 40×24

= 960
