Answer:
925 m^2 and Rs. 1,665
Step-by-step explanation:
Outer Length = 112m
Outer Width = 78m
Outer Area of plot = 112 × 78
= 8736 m ^2
Width of path = 2.5m
Inner Length = 112-(2×2.5)
= 107m
Inner Width = 78-(2×2.5)
= 73m
Inner Area = 107 × 73
= 7811m^2
Area of path = 8736 - 7811
= 925m^2
Cost = 925 × 1.8
= Rs.1665
