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
What is the surface area of her tent?
The answer is: The surface area of her tent s 56 feet².
