What is the surface area of the square pyramid represented by the net?

The surface area of the square bottom = L x W = 7 x 7 = 49 cm^2

The area for one of the triangles = 1/2 x base x height = 1/2 x 7 x 9 = 31.5 cm^2

There are 4 triangles, the total area for the triangles = 31.5 x 4 = 126 cm^2

Total area = base  + triangles = 49 + 126 = 175 cm^2

45

step-by-step explanation:

30+15
