Question 239597: Hey i need help solving this one problem:
The photograph shows the Pyramid of Khafre in Egypt. Each side of its square base is about 214 meters long. Each triangular side is an isosceles triangle with a height of about 179 meters. What is the area of one side of the pyramid?

Depends. Is the height you gave the slant height, that is the measure from the apex of the pyramid down the face of one side to the midpoint of one edge of the base, or is it the pyramid height from the apex to the center of the square base?

If it is the slant height, then just use the triangle area formula:

If it is the actual height of the pyramid, then you need to incorporate Pythagoras to get the altitude of the triangle:

Either way, you get to do your own arithmetic.
