A square pyramid has a square base and 4 triangles for the lateral sides.

Total Surface Area of the Pyramid = Area of the Base + 4 x area of one triangle

You are given area of the base and the Total surface area. From this you can find the area of all the 4 triangles. From this you need to calculate the area of one triangle
