a rectangu7loar field is to be enclosed with exactly 240 meters of fencing materials. if the length is 8 meters more than the width, find the dimensions of the field

Question

with solution pls.

Answer 1

let x=width
x+8=length
P=2L+2W
240=2x+2(x+8)
240=2x+2x+16
240=4x+16
240-16=4x
224=4x

x=56m (width)

Length=x+8
=56+8
=64m

Answer 2

checking:
240=4x+16
240=4(56)+16
240=240
