OlgaM077 [116]

Answer:

The surface area of the square pyramid is $144\ m^{2}$

where

B is the area of the base

P is the perimeter of the base

h is the height of the pyramid

Find the area of the base B

$B=6^{2}=36\ m^{2}$

Find the perimeter of the base P

$P=4*6=24\ m$

The height is $h=9\ m$

substitute the values

$SA=36+24*9/2=144\ m^{2}$
