Answer 2

Step-by-step explanation:

F first we have to find the perimeter of the rectangular park because fencing is always around the park not inside the park

hence ,

Perimeter = 2(l+b)

= 2(275+125) m

= 2* 400 m

= 800 m

By unitary method ,

cost of fencing of 1 metre = Rupees 15

cost of fencing of 800 metre = 800* Rupees 15

= Rupees 12,000
