What is the surface area, explain your work

The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.

Area of Square + 4*Area of Triangle = SA

Area of Square:
2^2=4

Area of Triangle:
0.5*2*3=3

SA=4+4*3
SA=16 meters squared
