A garden is 120 m long and 85 m board. A path 3.5 m wide is constructed all around inside the garden.Find the area of the path. Also find the remaining area of the garden.I.

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
