THIS IS FALSE!!
because if they give you that the perimeter is 130 and the flower bed is 40 feet long we would subtract 40 from 130 twice. lets do the math:)
130 - 40 - 40 = 50
and in order to find our width we divide 50 by 2. lets do the math:)
50 / 2 = 25!!
so our width here is 25 not 90
have a good one:)
