Question

Cost of cultivating a rectangular field at the rate of rupees 5 per metre is 2880 if the length of the field is 32 metre find the cost of fencing the field at the rate of rupees 11.25 per metre

Answer 1

Answer:

1125Rs.

Step-by-step explanation:

Area of field =2880/5 m=576m^2

then

l×b=576m^2

32m×l=576m^2

l=576m^2/32m

l=18m

then

perimeter of field =2(l+b)=2(18m+32m)=2×50m=100m

cost of fencing the field=Rs.100×11.25=Rs.1125ans..
