The length and breadth of a playground are 52m 60cm and 30m 40cm respectively. Find the cost of fencing it at the rate of Rs 5 per metre and the cost of levelling the ground at the rate of Rs 10 per square metre

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The cost of fencing and leveling the ground are Rs.830 and Rs.1599.04 respectively.

Step-by-step explanation:

100 cm = 1m

Length of playground = 52 m 60 cm = 52.6 m

Breadth of playground = 30 m 40 cm = 30.4 m

Perimeter of playground = 2(l+b)=2(52.6+30.4)=166 m

Cost of fencing 1 m = Rs.5

Cost of fencing 166 m = $Rs. 5 \times 166 = Rs.830$

Area of playground = $Length \times Breadth = 52.6 \times 30.4 = 1599.04 m^2$

Cost of leveling 1 sq.m. = Rs.10

Cost of leveling 1599.04 sq.m. =$1599.04 \times 10 = Rs.15990.4$

Hence The cost of fencing and leveling the ground are Rs.830 and Rs.1599.04 respectively.
