Question

a 360 m piece of barbed wire is to be fenced around a rectangle field. the length of the field is 5 times its breadth.

Answer 1

perimeter=2(l+b)
360=2(5b+b)
360=10b+2b
360=12b
360/12=b
30=b

breadth is 30m
length is 150m

area=l*b
A=150*30
A=4500m^2

Answer 2

Answer:

Breadth b= 30 m

Length = 150m

Area = l× h

= 30 × 150

= 4500 m²
