Question

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

Answer 1

let the breadth be x
b=x
l=5x
total length that will be barbed around the rectangular field = 360m
360m=perimeter of the rectangular field
360=2(x+5x)
360=12x
360/12=x
30=x
b=30m
l=150m
