Find the surface area of the square pyramid shown. Include all faces in your calculations.

A pyramid with a square base and four lateral faces is displayed. Each side of the square base is marked with single tick, measured as 4 cm in length. A slant height extending from one side of the base through the lateral face to the apex of the pyramid is measured as 7 cm. The slant height is perpendicular to the side of square base, indicated by a right angle symbol.
