The path of one metre wide runs around and inside a Square Garden of side 20 metre find the cost of levelling the park at the rate of rupees 2.25 per square metre

Answer 1

cost of levelling the park=20×20×2.25=900

Answer 2

The cost of levelling the park at the rate of rupees 2.25 per square metre is Rs.171

Step-by-step explanation:

Side of square garden = 20 m

The path of one metre wide runs around and inside a Square Garden of side 20 metre

So, Inner length = 20-(1+1)=18 m

Area of square = $side^2$

Area of Path = Outer Area - Inner area

Area of Path =$20^2-18^2$

Area of Path =$76 m^2$

Cost of leveling 1 sq.m. = 2.25

Cost of leveling 76 sq.m. = 2.25 \times 76 = Rs.171

Hence The cost of levelling the park at the rate of rupees 2.25 per square metre is Rs.171
