The area of the of the storefront window made of glass in question is = 154 square feet The length of the glass window that is given in the question is = 7 feet Let us assume the Width of the glass window in question to be = x feet Then Area = Length * Width 154 = 7 * x 7x = 154 x = 154/7 = 22 feet So we come to know that the width of the glass window in question is 22 feet. Now Perimeter of the glass window = 2 ( Length + Width) = 2 (7 + 22) meters = 2 * 29 meters = 58 meters. So the perimeter of the glass window as can be seen from the above deduction is 58 meters.
