PLEASE HELP ASAP!! Find the surface area of the regular pyramid shown in the accompanying diagram. If necessary, express your answer in simplest radical form.

A. 146.85 units²

B. 45+9√3 units²

C. 36+9√3 units²

D. 36+3√3 units²

The total surface area of the pyramid is 52 square units

The formula for calculating the area of the triangular based pyramid is expressed as;

where;

p is the perimeter of the base

s is the slant height

Get the Base area

Get the perimeter

Perimeter = 5 + 5 + 6

Perimeter = 16 units

Slant height = 5units

Substitute the given values into the formula above as shown;

Hence the total surface area of the pyramid is 52 square units
