Answer:
SQUARE PYRAMID
Given
Base (b) = 9 m
Slant height (s) = 4.5 m
Surface Area (S) = ?
Calculate the perimeter of the base.
P = 4b
P = (4)(9)
P = 36 m
Calculate the area of the base
A = b²
A = (9)²
A = 81 m²
Calculate the surface area of the square pyramid.
S = A + 1/2Ps
S = 81 + (1/2)(36)(4.5)
S = 81 + 81
S = 162 m²
