NOTE: https://brainly.in/question/1706923:
Given:
Length = 50m.
Breadth = 30m.
Height = 2.5m.
Area of floor = length * breadth
= 50 * 30
= 1500.
Area of 4 walls = Perimeter * height
= 2*2.5(50+30)
= 400
Total surface area of swimming pool = 400 + 1500
= 1900.
Cost of cementing its floor = 1900 * 27
= 51300.
Therefore the cost of cementing the floor = 51300.
