Step-by-step explanation:
What we want to do here is calculate the final cost, given the original price

Width = 5, length = 9
Area = length * width
length = (2 * width) - 1
sub equation for length
45 = (2w - 1) * w
45 = 2w^2 - w
2w^2 - w - 45 = 0
(2w - 9)(w - 5)
2w - 9 = 0
w = 9/2, l = 8 no
w -5 = 0
w = 5, l = 9 yes
