Question

A park of length 150m and breadth 80m has a uniform path of width 5m running all around the inside. the remaining area is to be covered by grass. find the cost of cementing the path at the path at the rate of rupees8.50 per m² and grassing at the rate of rupees2 per m²

Answer 1

Answer:

Step-by-step explanation:

length of path = length of park - width of path = 150 m - 5 m = 145 m

breadth of path = breadth of park - width of path = 80 m - 5 m = 75 m

area of park = 150 * 80 = 12,000 sq. m

area of path = 145 * 75 = 10,875 sq. m

cost of cementing = area of path * 8.50 = 10,875 * 8.50 = 92,437.5 rupees

cost of grassing = area of park * 2 = 12,000 * 2 = 24,000 rupees
