B. 1/4 there's only one 2 and there's for numbers is it going to be 1/4
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
