Answer:

Rs 7920


Step-by-step explanation:

Find the area of the garden:

Area = Length x Breadth

Area = 55 x 30 = 1650 m²


Find the area of the garden and the pathway:

Pathway = 1 1/2 m = 1.5 m

Area = (55 + 1.5 + 1.5) x (30 + 1.5 + 1.5)

Area = 1914 m²


Find the area of the pathway:

Area = 1914 - 1650 = 264 m²


Find the cost:

1 m² = 30

264 m² = 30 x 264 = Rs 7920


Answer: Rs 7920
