Answer:
200 ft^2
Step-by-step explanation:
The surface area of the pyramid is the sum of the area of the base and the areas of the 4 congruent triangular sides.
SA = LW + 4 * bh/2
SA = 10 ft * 10 ft + 4 * (10 ft)(5 ft)/2
SA = 100 ft^2 + 2(50 ft^2)
SA = 200 ft^2
(P.S. It's impossible to make a pyramid with these dimensions.)
