A = 1/2 (b*h)
if h = height
then b = 2h - 14
This should be enough for you to try to do the rest.
A triangle's base is 14 inches less than 2 times its height. If h represents the height in inches, and the total area of the triangle is 54, which of the following equations can be used to determine the height? A. 7h-h2=54 B. 2h2-14h=54 C. h2-7h=54 D. 14h-2h2=54
