Question

The perimeter of a rectangular field is 328 yards. if the width of the field is 72 yards, what is its length?

Answer 1

92

328-72-72=184

184/2=92

Answer 2

The perimeter is 328 yards and there are 2 widths in the rectangle. 
Add 72 and 72.
= 144 yards.
Subtract 144 from 328.
=184 yards.
Divide 184 by 2.
=92 yards.
So 92 yards is your length. I hope this helps love :)
