Question

The area of a triangle is 27 square feet its height is three times the length of its base find the height and base of the triangle

Answer 1

A = 1/2 * h * b
A = 27
h = 3b

27 = 1/2 * 3b * b
27 = 1/2 * 3b^2
27 * 2 = 3b^2
54 = 3b^2
54/3 = b^2
18 = b^2
sqrt 18 = b
4.24 = b <=== base

h = 3b
h = 3(4.24)
h = 12.72 <== height
