The answer is 6215.75 square inches. The area of the fabric is 4.81 square yards so taking the square root of that I get approx 2.19 yards. Checking, 2.19 x 2.19 yards = 4.81 sq yds. I yard is 36 inches so 2.19 x 36 = 78.84 inches and when this is squared ie 78.84 x 78.84 you get 6215.75 square inches.
