Question

Find the height of a triangle whose base is 25 inches and whose area is 75 square inches.

A. 3 inches
B. 3 square inches
C. 6 inches
D. 6 square inches E. 5 inches

Answer 1

C. 6 inches

Explanation:

Base = 25 inches

Area = 75 square inches

Using the formula

A = HbB/2

Solving for Hb

Hb = 2 A/b = 2 . 75/25 = 6 inches

Answer 2

Area formula:
(base x height) / 2 = Area

(25 x height) / 2 = 75
25 x height = 75 x 2
25 x height = 150
height = 150/25

height = 6 inches
