1. The tent has the shape of a square pyramid. Therefore, to solve this problem, you must apply the formula for calculate its surface area, which is:
A=2bs+b²
"A" is the surface area of the square pyramid. "b" is the side length of the square base (b=4 feet). "s" is the slant of the face (s=5 feet).
2. When you substitute these values into the formula for calculate the area of the square pyramid (A=2bs+b²), you obtain:
A=2bs+b² A=2(4 feet)(5 feet)+(4 feet)² A=2(20 feet²)+16 feet² A=40 feet²+16 feet² A=56 feet² <span> What is the surface area of her tent? </span> The answer is: The surface area of her tent s 56 feet².
