Answer» Let the outer rectangle be ABCD and the inner rectangle be abcd. Length and Breadth of the outer rectangle = 120 meter and 85 meter.Area of outer reactangle Ao = 120*85 = 10200 m^2 The uniform width of the inside path is 3.5 meter,So, the length of the inner rectangle = 120 - 7 = 113 mand the breadth of the inner rectangle = 85 - 7 = 78 mThe area of the inner rectangle Ai = 113× 78 = 8814 m^2 The area of path= Ao - Ai= 10200 - 8814= 1386 m^2 Remaining area = area of inner rectangle = 8814 m^2 |
