Find the Error Pilar is finding the surface area of the pyramid shown.
Find her mistake and correct it.

Persevere with Problems The lateral surface area LA. of a pyramid is the area of its lateral faces. Use the square pyramid at the right to complete each step to find  the lateral surface area of any pyramid.

\(
\begin{aligned}
L.A.&= \frac{1}{2}sl \ +\\
&= \frac{1}{2} ( \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ )l \\
&=
