Emma is going camping. Each side triangle on her tent is 5 feet tall. The square base is 4 feet wide. What is the surface area of her tent?

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.
