Question

find the height of a triangle with an area of 156 sq inches and the base of 8 inches. Use the formula A=1/2bh

Answer 1

height = 39 inches

Explanation:

The area (A) of a triangle is calculated as

A =
`(1)/(2)`bh ← b is the base and h the height

Here b = 8 and A = 156, thus

`(1)/(2)` × 8 × h = 156, that is

4h = 156 ( divide both sides by 4 )

h = 39

The height of the triangle is 39 inches

Answer 2

Explanation:

A = 1/2 bh

1/2 bh = A

1/2 * 8 *h = 156

8*h = 156 * 2

h = 156 * 2 / 8

h = 156/4 = 39

h = 39 inches
