base: b
height: 5b - 2
Area = 1/2 (b) (h)
36 = 1/2(b) (5b - 2)
72 = b(5b - 2) <em>multiplied both sides by 2 to clear the denominator</em>
72 = 5b² - 2b
0 = 5b² - 2b - 72
Use quadratic formula to find that b = 4 or -3.6 (disregard the negative) so
b = 4
height: 5b - 2 = 5(4) - 2 = 20 - 2 = 18
Answer: base=4 in, height=18 in






We can rule out the negative length.

Answer: b=4, h=18
