Question

Find the surface area of the isosceles trapezoid prism , Do not round answer

Answer 1

From the question;

The Area formula for a trapezoid is;

`\begin{gathered} B=(1)/(2)h(b_1+b_2) \\ Where\text{ B=Area} \\ h=\text{height of the trapezoid} \\ b_1,b_2=bases_{} \end{gathered}`

So, we have the surface area as;

`\begin{gathered} SA=ph+2B \\ \text{Where SA= surface area} \\ p=\text{perimeter of the trapezoid} \\ h=\text{height of the prism} \end{gathered}`

But the perimeter p of the trapezoid is;

Thus, we have;
