**MathMate**, Wednesday, February 29, 2012 at 9:34pmThe lateral surface area of a pyramid (the slanted sides) is the perimeter of the base P multiplied by the slant height H and divided by two, or

A(lateral) = PH/2

Finally multiply by the price per metre^2 to get the price.

The perimeter of the square base is therefore 4*18.

Useful information:

"18m x18m " is a short form for "each side of a square is 18m"
