49 tiles because a square has the same length as it does breadth. The Area of a square is length times breadth, so if length eqauls seven then so does the breadth which means that the area will be 7x7 which eqauls 49.

Given that the area of a rectangle is represented as A=l x w, where l =length, and w=width, and that a square is just a rectangle where all the sides are the same, the area of this square would = 2 feet x 2 feet. That yields a prodcut of 4 square feet, which is the area you would need to cover in poured concrete.
5 ft by 9 ft is 45 square feet. This requires 6,480 square inches to cover it.
