Answer:
Step-by-step explanation:
Area of path = Area of outer rectangle - Area of grassy plot
length of plot = 75m, breadth = 60m
∴Area of plot = l * b = 75*60
= 4440m²
length of rectangle formed = 75 + 2 + 2 = 79
breadth = 60+2+2 = 64
∴Area of big rectangle = 79*64
=5056
∴Area of path = 5056 - 4440 = 616m²
∴cost of path = 3.6*616 = Rs 2217.6
