Answer 2

Given,

Length of the swimming pool = 50 m

The breadth of the swimming pool = 30 m

Height of the swimming pool = 2.5 m

Cost of cementing 1 m² = ₹27

To find,

We have to find the cost of cementing the floor and walls of the swimming pool.

Solution,

The cost of cementing its floor and walls at the rate of ₹27 per square meter is ₹51300.

We can simply find the required area to be cemented by using the formula,

      Area of 4 walls + base = 2h(l+b) + lb

   Required area = 2 * 2.5(50+30) + 50(30)

                            =     5(80) + 1500

                            =       1900 m²

Cost of cementing the floor and the walls of 1 m² = ₹27

Cost of cementing the floor and the walls of 1900 m² = 27 * 1900

                                                                                            = ₹51300

Hence, the cost of cementing its floor and walls at the rate of ₹27 per square meter is  ₹51300.
