Question

4. The area of a triangle measures 54 in? The height of the triangle is 18 inches. What is the base of the triangle? Base =

Answer 1

The area of a triangle is computed as follows:

`A=(b\cdot h)/(2)`

where b is the base, and h is the height

Replacing with A = 54, h = 18, and solving for b, we get:

`\begin{gathered} 54=(b\cdot18)/(2) \\ 54\cdot2=b\cdot18 \\ (108)/(18)=b \\ 6=b \end{gathered}`

The base of the triangle is 6 in
