Question

The formula for the area of a triangle is , where b is the length of the base and h is the height.

Find the height of a triangle that has an area of 30 square units and a base measuring 12 units.

Answer 1

Area = (1/2)bh. Substitute b = 12 and area = 30:

(1/2)(12)h = 30
6h = 30
h = 30/6 = 5

The height is 5 units.
