Answer 1

A square pyramid has a total surface area of one thousand square feet. The area of the base is two hundred square feet. What is the area of one triangular face of the lateral surface?

one hundred twenty-five square feet

one hundred fifty square feet

one hundred seventy-five square feet

two hundred square feet

Answer 2

square pyramids have four lateral sides and one base
you already know the base = 200
therefore the 4 lateral sides total = 1000-200=800

one lateral side would be 800÷4=200
