In a lateral face of a regular square pyramid, an altitude is drawn from a base vertex to the opposite lateral edge contained by the same face. The angle formed by this altitude and the base edge of the same lateral face is 20°. Find the surface area of the pyramid if the base edge is 7 cm long. Round your answer to the nearest cm².
