A = 58.5 h = 9 b = ?
..............................................

Area of a triangle
Formula : A = 1/2 * b * h

Substitute A for 58.5 and h for 9.

A = 1 * b * h
2
58.5 = 1 * b * 9
2
58.5 = 9b
 2

Cross Multiply

9b = 117
b = 117
9
b = 13

Area of a triangle = 1/2 x base x height
a = 58.5
height = 9

58.5 = 1/2 x base x 9
58.5 = 4.5 x base
base = 13
