Question

What is the area of the triangle prism ? use a net .

Answer 1

To determine which formulas we need to use we first need to identify the figures that form each face. The sides and the bottom of the prism are rectangles, while the front and the back are triangles. We need to use the formula for these figures. They are:

`\begin{gathered} A_{\text{rectangle}}=length\cdot width \\ A_{\text{triangle}}=(base\cdot height)/(2) \end{gathered}`
