Answer 2

Given :

Length of playground = 30 m

Breadth of playground = 15 m

To Find :

Find the cost of levelling a playground at rupees 3 per square metre if it is 30 M long and 15m wide also find the cost of fencing it at rupees 1.20 per metre

Solution:

Length of playground = 30 m

Breadth of playground = 15 m

Area of playground =$length \times Breadth = 30 \times 15 = 450 m^2$

Cost of leveling 1 sq.m. = Rs.3

Cost of leveling 450 sq.m. =$450 \times 3 =Rs.1350$

Perimeter of playground =2(l+b)=2(30+15)=90 m

Cost of fencing playground 1 m = rs.1.2

Cost of fencing playground 90 m =$1.2 \times 90=108$

Hence The cost of leveling a playground  is rs.1350 and the cost of fencing is rs.108
