The length of the base of a square pyramid is 9 inches. The slant height is 12 inches. What is the surface area of the pyramid?

Question

anonymous · Answer

surface area for a pyramid is SA= 1/2  Pℓ + B
so if you plug in those numbers it would be 1/2 (36*12) + 81
do you think you can solve it from there and understand how I got that?
