Question

The perimeter of the rectangular park is 180 m. If the length of the park is twice its width, find the breadth of the rectangular park.

Answer 1

let the breadth of park is x then length be 2x

Perimeter=2 (l+b)

180=2 (x+2x)

90=3x

x=30

breadth of park is 30m

Answer 2

Breadth=30 cm

Step-by-step explanation:

let length be l

and breadth be b

l=2b

perimeter=2(l+b)

180=2(2b+b)

180=2 X 3b

180=6b

b=180/6

b=30
