You just put in calculator make sure you click the mode button and highlight degree so it can work
208 in^2
find the area of each of the parts (4 triangles and 1 square)
all of the triangles have the same area since this is a square pyramid
area of triangle = (base X height)/2
so it would be (8 X 9)/2 = 36
for the square, the area is length X width
so it would be 8 X 8 = 64
add all the areas
36+36+36+36+64 = 208
