Question

A rectangular shaped swimming pool with dimensions 30m×20m has 5m wide cemented pathalong its lenght and 8m wide path along it's width find the cost of cementing the path at the rate of₹200 per m×m

Answer 1

200 × (30×8)

48000

₹ 48,000

Answer 2

A rectangular shaped swimming pool with dimensions 30mx20m

Length = 30 m

Width = 20 m

Area = 30 * 20 = 600 m²

5m wide cemented path along its length

=> Width = 20 + 5 + 5 = 30 m

8m wide path along it's width => Length = 30 + 8 + 8 = 46 m =

Area including path = 30 * 46 : = 1380 m²

Area of Path = 1380 - 600 = 780 m²

Rate of cementing the path =200 per =

m²

the cost of cementing the path = 780 *

200 = Rs 156000
