Length of the rectangular patio = 12 1/2 feet = 25/2 feet Area of the rectangular patio = 103 1/8 square feet = 825/8 square feet Let us assume the width of the rectangular patio = x feet Then Area of the rectangular patio = Length * Width 825/8 = (25/2) * x 25x/2 = 825/8 25x = (825 * 2)/8 feet 25x = 825/4 feet x = 825/(4 * 25) feet = 33/4 feet = 8 1/4 feet So the width of the rectangular patio is 8 1/4 feet. I hope the procedure is clear enough for you to understand.
