Rs is required to pave the path
15×25=375 (area of rectangle=l×b)

Im not sure abt it hope its correct just tryed my best to help u

Answer 2

The cost of paving the path​ is Rs.2160

Step-by-step explanation:

Length of field = 25 m

Breadth of field = 15 m

Area of filed =$25 \times 15 = 375 m^2$

Width of path = 2 m

Inner length = 25m -(2+2)m=21 m

Inner breadth = 15 m - (2+2)m = 11 m

Area of Inner =$Length \times Breadth = 21 \times 11 = 231 m^2$

Area of path = Outer area - inner area=$375 - 231 = 144 m^2$

Cost of paving 1 sq.m. = rs, 15

Cost of paving 144 sq.m. = $15 \times 144 = Rs.2160$

Hence  the cost of paving the path​ is Rs.2160
