A cement path 1 meter wide was built around a swimming pool 20 meters x 30 meters.what is the total area at the cemented path
Answers
Answer:
Step-by-step explanation:
Rs 156000 is the cost of cementing the path at the rate of ₹200 per m×m
Step-by-step explanation:
A rectangular shaped swimming pool with dimensions 30m×20m
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
Answer:
Area of cemented path = (area of total swimming
pool + 1 meter in both the dimensions) - area of swimming pool
∴ L*B - l*b
= 21*31 - 20*30
= 651 - 600
= 51 m²
∴ THE AREA OF THE CEMENTED PATH IS 51 m²
