Examples based on Finding the cost of fencing of a rectangular field
Example 1
Find the cost of fencing of a rectangular field 65 m long and 55 m wide at ₹ 10 per metre?
Explanation
Length of the field = 65 m
Breadth of the field = 55 m
Perimeter of the field = 2 ( l+b ) units
Perimeter of the field = 2 ( 65 + 55 ) m
Perimeter of the field = ( 2 x 120 ) m
Perimeter of the field = 240 m
Cost of fencing per metre = ₹ 10
Total cost of fencing = ₹ ( 240 x 10 ) = ₹ 2400
Example 2
Find the cost of fencing of a rectangular field 100 m long and 50 m wide at ₹ 12 per metre?
Explanation
Length of the field = 100 m
Breadth of the field = 50 m
Perimeter of the field = 2 ( l+b ) units
Perimeter of the field = 2 ( 100 + 50 ) m
Perimeter of the field = ( 2 x 150 ) m
Perimeter of the field = 300 m
Cost of fencing per metre = ₹ 12
Total cost of fencing = ₹ ( 300 x 12 ) = ₹ 3600
