Answers
Answer:
1925
Step-by-step explanation:
For Rs.24, then length of fencing =1m
For Rs.52 so, the length of fencing
=
24
1
×5280=220meters
Circumference of the field =220m
2pr=220
Therefore r=
44
220×7
=35m
Area of the field =πr
2
π(35)
2
=1225
Cost of ploughing =Rs.0.50 per m
2
Total cost of ploughing the field =Rs.1225
=
7×2
1225×22×1
=Rs,1925.
Hence, the answer is 1925.
Total cost of ploughing the field is = 1925
Circumference of the field is = 220m
For Rs.24, then length of fencing =1m
For Rs.52 so, the length of fencing = 24
1 ×5280=220meters
Circumference of the field =220m
2pr=220
Therefore r= 44
220×7 =35m
Area of the field =πr
2 π(35) 2 =1225
Cost of ploughing =Rs.0.50 per m 2
Total cost of ploughing the field =Rs.1225
= 7×2
1225×22×1
=Rs,1925.
Hence, the answer is 1925.
