Question

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

Answer 1

length =45m
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

Answer 2

given length of rectangular field is 45cm and breadth is 15 less than it
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
