The surface area of a pyramid can be calculated using the formula: Area = 1/2 * base perimeter * slant height + base area.
In this case, the base perimeter is 4 ft + 4 ft + 4 ft + 4 ft = 16 ft and the slant height is 7 ft.
Plugging these values into the formula: Area = 1/2 * 16 ft * 7 ft + 4 ft * 4 ft = 56 ft^2 + 16 ft^2 = 72 ft^2.
Therefore, the surface area of the pyramid is 72 ft^2.
The closest answer choice is 72 ft2.
