400
A rectangle has a length that is 5 inches and a width that is 2x + 4 inches long. If the area of the rectangle is 100 inches squared, what is the PERIMETER of the rectangle?
50 inches
Area = 5(2x+4)
100 = 10x + 20
80 = 10x
8 = x
Perimeter = 5 + 5 + (2x + 4) + (2x + 4)
Perimeter = 5 + 5 + 20 + 20
Perimeter = 50in
