The height of a parallelogram is 5 feet more than its base. If the area of the parallelogram is 204 square feet, find its base and height.

base of a gm is
base x height
base  x
height  x+5
s(x+5) = 204
x^2 + 5x  204 = 0
(x12)(x+17) = 0
x = 12 or a negative
base is 12, height is 17 
How long is the base of a parallelogram with an area of 84 square feet and a height of 12 feet

base of a gm is
base x height
base  x
height  x+5
s(x+5) = 204
x^2 + 5x  204 = 0
(x12)(x+17) = 0
x = 12 or a negative
base is 12, height is 17
