Question

The cost of a fencing a circular field at the rate of rs24 per metre is rs5280 .Find it’s area of the field

Answer 1

For Rs. 24 , the length of fencing =1m
For Rs. 5280, the length of fencing = 5280 = 220 metres.
Circumference of the field = 220 m
2pr =220
2x r =220
Area of the field = r2 = (35)2 =1225 m2
Cost of ploughing = Rs. 0.50 per m2
Total cost of ploughing the field = Rs. 1225 x 0.50
= Rs.
