Question

find the dimension of the missing side of a triangle given the following measurements: A=75 sq. ft, b=15 ft, h=?

Answer 1

h = 10 ft

Explanation:

The area (A) of a triangle is calculated as

A =
`(1)/(2)` bh

Here A = 75 and b = 15, thus

`(1)/(2)` × 15h = 75 ( multiply both sides by 2 to clear the fraction )

15h = 150 ( divide both sides by 15 )

h = 10
