Question

The area of a triangle is 24 square inches. What is the height of the triangle if the base length is 8 inches?

Answer 1

6 is the height of the triangle . 
The formula for a triangle is 1/2 bh  

Answer 2

The formula for the area of a ∆ is 1/2bh. So since you already have the area, solve for x.
24=$\frac{1}{2}$(8)x
24=4x
6=x
The missing side is 6 inches long.
