Question

The area of a triangle equals 15 square inches. What is the altitude, a, of the triangle in terms of its base, b?

Answer 1

$\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh\qquad \begin{cases} b=base\\ h=\textit{height or altitude}\\ ----------\\ A=15 \end{cases}\implies 15=\cfrac{bh}{2}$

solve for "h" or altitude
