A rectangular plot 85 m long and 60 m broad is to be covered with grass leaving 5 m all around. Find the area to be laid with grass.

Given:

The length of the rectangular field is 85 m.

The breadth of the rectangular field is 60 m.

The width of the path to be covered with grass is 5 m.

The length of the inner rectangular field = 85 m - 5 m - 5 m = 75 m

The breadth of the inner rectangular field = 60 m - 5 m - 5 m = 50 m

The area of a rectangle = length x breadth

⇒ Area of the inner field = 75 x 50 m² = 3,750 m²

Hence, the area to be covered with grass is 3,750 m².
