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

=500m

→ Cost of constructing =24.50 per square m.
=500m

=2684m2−2184m2
=500m2
→ Cost of constructing = Rs.5 per square m
= 500 m²×5
= 2500
