The shortest distance between edge of rug(circle) and the side of square is given 17.5 feet. The shortest distance is the distance measured parallel to the side of the square, not the one parallel to the diagonal of the square.
therefore, side of square = diameter or circle + 2*17.5
given circumference of circle = 236 feet
2*pi*r=236
2r=75.09
side of square = 75(approx)+35 = 110
Area of square = 110*110 = 12100
therefore, side of square = diameter or circle + 2*17.5
given circumference of circle = 236 feet
2*pi*r=236
2r=75.09
side of square = 75(approx)+35 = 110
Area of square = 110*110 = 12100
