**MathMate**, Thursday, May 12, 2011 at 12:07pmThe lateral area of a pyramid can be calculated by the following formula:

Area, A = pa/2

p=permimeter of the base polygon

a=apothem of the pyramid, i.e. the slant height.

Therefore, the slant height (or the apothem, a) can be calculated as follows:

a = 2*lateral area/perimeter of base

= 2A/p

**JOY**, Thursday, May 12, 2011 at 12:49pmHow do I find the perimeter of base

is it 18

**MathMate**, Thursday, May 12, 2011 at 2:46pmYes, 18 is correct.

A hexagon has 6 sides, each of length 3 ft. So

Perimeter, p = 6*3 ft = 18 ft.
