Question

The area of a triangle is 30 square inches. What is the length of the base if the height is 6 centimeters?

Answer 1

x = 10 cm

Explanation:

The area (A) of a triangle is calculated as

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

Here b = x, h = 6 and A = 30 , then

`(1)/(2)` × 6 × x = 30

3x = 30 ( divide both sides by 3 )

x = 10
