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

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
