Question

lateral height (l) if height of the pyramid (3) and half the length of the base (1).

Answer 1

Clarify this, please.

Answer 2

What are we supposed to find?

Answer 3

Total Area

Answer 4

I got to this \[l ^{2 } = 10 but not sure how to simplify

Answer 5

\[A=B+\frac{PL}{2}\]
B is the base area, P is the base perimeter, and L is the slang height. You can get L by solving the triangle in your picture. Use the fact that the small leg is implied and solve for the hypotenuse (which is the slang height).

Answer 6

\[l ^{2} = 10\]
