# A rectangular field is 45m long and its breadth is 15 m less than its length.find the cost of turfing it at the rate of Rs 2 per sq.meter .Also find the cost of fencing it at the rate of Rs 3.50 per meter

breadth=l-15=30m

area = lxb=45x30 =1350m sq

1m sq=Rs2

1350m=1350x2=Rs2700

*for the fencing we need perimeter

2(l+b) =2(45+30)=150m

cost of 1m=Rs3.50

cost of 150m=3.50x150=Rs525 ans

therefore breadth is 45-15 equals 30

therefore area will be 30*45 equals 1350cm sq.

rate

cost of turfing will be 1350*2 equals 2700

perimeter will be 2(45+30)

2(75)

150

therefore cost of fencing will be 150*3.5 equals. 525
