Question

Find the cost of fencing a rectangular park of side 20m and

10m at the rate of 29 Rs. per metre.​

Answer 1

Answer:

Length of rectangular park = 20m

Breadth of rectangular park = 10m

Perimeter of rectangular park = 2 (l+b) = 2 ( 20 + 10 ) = 2 x 30 = 60m

Cost of fencing 1m = 29/-

Cost of fencing rectangular park

                    = Cost of fencing 60m

                    = 60 x Cost of fencing 1m

                    = 60 x 29

                    = 1740/-
