James Wiggins · Answer 1

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

Adison Maynard · Answer 2

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
