Question

The fence around a field 108 m long and 80 m wide
needs to be painted. How much would the job cost if
it costs ₹11 to paint 1 metre of the fence?
​

Answer 1

Answer:

Given

• A field of length = 108m and width = 80m
• Cost of painting 1 metre = 11rs.

To find

• Cost of painting the total fencing of field

Solution

Hence, the field is rectangular

So, its perimeter = 2(l + b)

= 2(108 + 80)

= 2 X 198

= 396m

• Cost of painting 1 metre = 11rs.

So, the cost of painting 396m

= 11 X 396

= 4356rs.
