Question

The area of a triangular road sign is 70 square ft. If the base of the sign measures 14 ft, what is the height of the sign?

Answer 1

height = 10 ft

Explanation:

the area (A) of a triangle is calculated as

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

given A = 70 and b = 14 , then

`(1)/(2)` × 14 × h = 70

7h = 70 ( divide both sides by 7 )

h = 10 ft
