Question

9. The length and breadth of a rectangular park are in the ratio 3:2 and its perimeter is
160 m. Find the area of the park.​

Answer 1

Answer:

5120

Step-by-step explanation:

Let,

the length be 3x and breadth be 2x.

perimeter=160

160=3x×2x

160=5x

x=160/5

32

Area=l×b

160×32

5120

Answer 2

Answer:

let the common factor be x

the ratio of l:b = 3:2

so the length = 3x

the breadth=2x

perimeter= 2*(l+b)=160m

3x + 2x= 80 (reason by dividing 160 by 2)

5x=80

x=80/5

x= 16

so the length is 3*16=48m

the breadth is 2*16=32m

area= L*B

48*32=1536 m square
