Question
### Question 5

**What is the lateral area of the pyramid shown below?**

#### Lateral Area of a Pyramid:

\[ \text{Lateral Area}_{\text{Pyramid}} = \frac{1}{2} PL \]

- \( P_{\text{square}} = 4s \); \( s \) = side length

#### Use the Pythagorean theorem to solve for slant height, \( L \):

\[ 10^2 + L^2 = 26^2 \]

#### Diagram Details:

- The figure is a square pyramid with a square base.
- The side length of the base, \( s \), is 20 ft.
- The vertical height from the base to the apex is 20 ft.
- The slant height, \( L \), is a diagonal distance from the middle of one side of the base to the apex, forming a right-angled triangle with half of the base side (10 ft) and the vertical height (20 ft).

Your response should show all necessary calculations and diagrams.
