student : The surface area of a pyramid is 189 cm squared The area of the square base is 49 cm squared. What is the area of one triangular face of the lateral surface? Show the steps of your solution and explain your work.

tutor3 : Please wait, we are helping other students
student : ok.
tutor3 : As stated, the question cannot be answered. The pyramid could be irregular so that its triangular faces have different areas.

If it were a regular pyramid, then with a square base it has four triangular faces whose combined area is
189 - 49 = 140 cm2

So each triangular face has an area of 140/4 = 35 cm2
