Answer:
The above picture is for the figure of tge question.
Firstly, Area of ABCD = length × breadth
= 15m × 12m
= 180m^2
PQ = RS = 15m - (1.5m + 1.5m)
= 15m - 3m
= 12m
PS = QR = 12m - (1.5m +1.5m)
= 12m - 3m
= 9m
Area of PQRS = PQ × QR
= 12m × 9m
= 108m^2
Area of the path = 180m^2 - 108m^2
= 72m^2
Rate of surrounding the garden = 72 × 22.25
= 1602 rupees
