Question

rectangular shaped swimming pool with dimensions 40 m × 30 m has 5 m wide cemented path along its length and 8 m wide path along its width. Find cost of cementing the path at the rate of Rs. 300 per square meter.

Answer 1

Answer:

Area covered by swimming pool = 30 m × 20 m= 600 m2.  Length of outer rectangle = (30 + 8 + 8) m = 46 m and its breadth = (20 + 5 + 5) m = 30 m  So, the area of outer rectangle = 46 m × 30 m = 1380 m2.  Area of cemented path = Area of outer rectangle – Area of swimming pool  = (1380 – 600) m2 = 780 m2.  Cost of cementing 1 m2 path =  200  So, total cost of cementing the path  =  780 × 200  =  156000

Answer 2

Step-by-step explanation:

Area covered by swimming pool = 30 m × 20 m= 600 m2. Length of outer rectangle = (30 + 8 + 8) m = 46 m and its breadth = (20 + 5 + 5) m = 30 m So, the area of outer rectangle = 46 m × 30 m = 1380 m2. Area of cemented path = Area of outer rectangle – Area of swimming pool = (1380 – 600) m2 = 780 m2. Cost of cementing 1 m2 path =  200 So, total cost of cementing the path =  780 × 200 =  156000Read more on Sarthaks.com - https://www.sarthaks.com/840506/rectangular-shaped-swimming-with-dimensions-wide-cemented-path-along-length-path-along
