Question

The area of a triangle is 225 in^2. If the width is 18 inches, find the height of the triangle

Answer 1

$\textit{area of a triangle}=\cfrac{1}{2}\cdot b\cdot h\qquad \begin{cases} b=\textit{base of triangle,}\\ \qquad \textit{may also be its width}\\ h=\textit{height of triangle} \end{cases} \\ \quad \\ b=width=18\qquad area=225 \\ \quad \\ 225=\cfrac{1}{2}\cdot 18\cdot h\impliedby \textit{solve for "h"}$
