1/2 times the perimeter of the base times slant height

The height of the triangular face of a pyramid is called the slant height.

Lateral Area=Perimeter of the base * height perimeter=20 height=6 so, Lateral Area=20 * 6 Lateral Area=120cm

The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

It is the lateral area (which is 1/2 the perimeter multiplied by the slant height), plus the area of the base.

You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.

Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
