We know that
surface area of the square pyramid=area of the base+4*[area of lateral triangle]
area of the base=b²----> area of square
b=6 ft
area of square=6*6---> 36 ft²
area of lateral triangle=b*h/2
b=6 ft
h=9 ft
area of lateral triangle=6*9/2---> 27 ft²
surface area of the square pyramid=36+4*27----> 144 ft²
the answer is
144 ft²

Answer:
3 1/5 square units
Step-by-step explanation:
4 units * 4/5 shaded
4*4/5 = 16/5
Changing to a mixed number
5 goes into 16 3 times with 1 left over
3*5 = 15 16-15 = 1
3 1/5 square units
