Question

The perimeter of a rectangular field is 396m.the length of the field is 8m more than its width.find the length and width of the field

Answer 1

let the length be x
width =x-8
2(x+x-8)=396
4x-16=396
4x=412
x=412÷4
x=103
width=95

Answer 2

perimeter = l × b
396 = ( x+8) (x)
396= 2x+8
396-8=2x
388=2x
x=194
b=194
l=194+8
=202
