Question

If a path surrounding a garden of length 10 m and breadth 7 m, where the width of the path is 2 m is

paved at a cost of Rs 15/m2

, Find the cost of paving it.​

Answer 1

Answer:

Rs 1260

Step-by-step explanation:

Length of Garden = 10 m

Breadth of Garden= 7 m

Area of Garden = length × breadth

= 10 m × 7 m = 70 m²

Width of path surrounding the garden = 2 m

Now Length of garden including the path = 10m + 4m = 14 m

breadth of garden including the path = 7m + 4m = 11m

Area of garden including the path= 14m × 11 m

= 154 m²

Area of path = Area of garden including the path - Area of Garden

=> 154 m² - 70 m² = 84 m²

Rate of paving = Rs 15/m²

Total cost of paving the path = Area of path × rate of paving/m²

=> 84m²× 15/m²= Rs 1260
