Question

The area of a triangle is 36 square inches (in^2). It's altitude (h) is 9 inches. How long is it's base?

Answer 1

The length of the base can be determined as,

`\begin{gathered} A=(1)/(2)bh \\ 36in^2=(1)/(2)b(9in) \\ b=(36in^2*2)/(9in) \\ b=8in \end{gathered}`

Thus, the length of the base is 8 in.
