To find the SA of square pyramid, remember that you must add up the surface areas of all of the shapes that make it up, for instance, here you would need to add the area of the bottom the square to the total area of all 4 triangle faces.
SA = area of square + 4(area of triangle)
SA = 2 m^2 + 4((2m • 5m)/2)
SA = 4 m^2 + 4(5 m^2)
SA = 4m^2 + 20 m^2
SA = 24 m^2.
I believe this would be the solution.
