Question 600366: The area of a rectangle is 27 square feet. The base is 3 more than twice the height

I assume you're looking for the rectangle's dimension
base = b
height = h
b = 3 + 2h
Area = b * h
27 = (3 + 2h)*h
factorize it into:
2h + 9 = 0 or h - 3 = 0
2h = -9 or h = 3
h = -9/2 or h = 3
because the height can't be a negative number, so h = 3
b = 3 + 2*3 = 3 + 6 = 9
so the height is 3 ft and the base is 27 ft
