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
