Question

A field is in the shape of a rectangle whose length is 130cm and

breath is 95m respectively. Find the cost of fencing the field at Rs 20

per metre.​

Answer 1

Answer:

2(1.3+95)×20

= 193.2× 20

= 1932 x 2

= 3864

Answer 2

Answer:

We know that fencing is always done in the perimeter .

Thus , perimeter of the rectangle =2(l+b)

[130 cm =1.3 m ]. = 2(1.3+95) m

= 2 x 96.3

= 192.6 m

Therefore , cost of fencing = perimeter x cost/m

= 192.6 x 20

= 3852 rupees .
