Answer:
Length of plot =56m
Breadth of plot =39m
Area =l×b
=56m×39m
=2184m^2
→ In rectangle ABCD
Length =56m+2.5m+2.5m
=61m
Breadth =39m+2.5m+2.5m
=44m
Area =l×b
=61m×44m
=2684m^2
→ Area of path = Area of ABCD− Area of plot
=2684m −2184m^2=500m
→ Cost of constructing =24.50 per square m.
=500m^2. ×24.50
=22250 Ans.
