Question

Find the cost of fencing a
rectangular field of length 20m
and breadth 16m at the
rate of a 15 per​

Answer 1

Length of field = 20 m

Width of field = 16 m

Perimeter of field = 2(l+b) unit

= 2(20+16) m

=72 m

Rate = 15 per m

Cost = 15 * 72

=1080

Answer 2

Answer:

perimeter of rectangle - 2 * ( l+b )

- 2* (20+16)

-2*(36)

- 72

Cost of fencing per m - 15

cost of fencing 72m- 15*72

- 1080
