Answer 1

Answer:

The length of a park is 4 times its breadth. Find the breadth of the park if

the perimeter is 420m.

Step-by-step explanation:

perimeter = 2(lb+bh+hl)

Answer 2

Let the breadth be 'x'

let the length be 4x

Perimeter=420 m

2(l+b)=420

2(4x+x)=420

2×5x=420

10x=420

x=420/10

x= 42m

length=4x=4×42=168m

Breadth=x=42 m
