Question

A section of the floor is to be covered with flooring boards measuring 1cm by 20cm. How many flooring boards are needed for covering the section of the floor?

Answer 1

Answer:

Given

The floor 5m by 20m (total surface area is 100m) and the tiles are 20cm;

 

1cm = 0.01m

 

so

 

20cm = 0.2m

 

The area of each tile would be 0.2m * 0.2m = 0.04m

 

To find the total number of tiles needed, we'll divide the size of the total surface area(100m) by the area of each tile(0.04m)

 

100m / 0.04m = 2500.

 

So 2500 tiles are needed.
