Question

find the surface area of the pyramid round to the nearest tenth choose the correct unit

Answer 1

slant height(h) = 16.3ft

Base side = 20ft

$\text{Area of pyramid=}\frac{1}{2\text{ }}\times perimeterofbase\text{ x slant height}$

Perimeter of base = 4(base side) = 4(20) = 80ft

$\begin{gathered} \text{Area of pyramid = }\frac{1}{2}\times80\times16.3 \\ \text{Area = }652ft^2 \end{gathered}$
