Question 295463
width = w
length = x
w = x - 5
area = 36
w * x = 36
(x - 5) * x = 36
{{{x^2 - 5x = 36}}}
{{{x^2 - 5x - 36 = 0}}}
{{{(x - 9)(x + 4) = 0}}}
x - 9 = 0 or x + 4 =0
x = 9 or x = -4


because the length can't be in negative number, so the length is 9 inches, and the width is x - 5 = 9 - 5 = 4 inches
