Question

A rectangular plot is 110 m long and 70 m broad. It has a gravel path 3 m wide all around
it. Find the area of the path and the cost of levelling it at the rate of 3.50 per sq. m.
12A lot is in the form​

Answer 1

Step-by-step explanation:

Length of rectangular plot = 110m

Breadth of rectangular plot = 70m

Width of gravel = 3m

so 110m + 3m = 113m

70m + 3m = 73m

Area of both the rectangles:

First: 110m*70m

7700m²

Second: 113m*73m

8249m²

8249m²-7700m² = 549m²

Cost of levelling = ₹3.50per m²

549*3.50 = ₹1921.5
