Whatever It Takes To Help
Picture a 5-same-sided bottom topped by 5 identical isosceles triangles. Both the given area and perimeter can be divided by 5 to get the area and base of one triangle. The slant height can be found by dividing the area of one triangle by half of its base.

I believe that you are referring to triangle(s) when you say pyramid(s).07/27/20
