How do you find the surface area of a pentagon based pyramid with slant height of 11 meters and a side length of 3 meters?

Calculate the area of the 5 individual triangles that make the pyramid and the area of the pentagonal base and add these six areas together.

Atriangle = 1/3 Base x Height

Apentagon = (Perimeter x Apothem)/2

Apothem = side length/(2Tan(∏/Number of sides))
