$A=240 \text{ } ft^2$

Work Step by Step

Using the formula for the area of a triangle which is given by $A=\dfrac{1}{2}bh,$ the area of a triangle with $h=30$ and $b=16$ is \begin{array}{l}\require{cancel} A=\dfrac{1}{2}bh \\\\ A=\dfrac{1}{2}(16)(30) \\\\ A=\dfrac{1}{\cancel2}(\cancel2\cdot8)(30) \\\\ A=240 \text{ } ft^2 .\end{array}
