Question

the perimetre of a rectangular field is 360 m. if its length is 100 m , find its area . if the rate of ploughing is Rs.12 per m ² . find its total cost.​

Answer 1

Answer:

Given: Length of the rectangular field=110 m

Breadth of the rectangular field=85 m

Perimeter of the rectangular field=2(l+b)

=2(110+85)=2×195

Perimeter of the rectangular field=390 m

2

Cost to fence the field per metre=Rs.25

Cost to fence the field 390 metre=Rs.25×390=Rs.9,750‬

∴ Cost of fencing the field =Rs.9750
