Question

A rectangular floor of area 30.24 m2 is going to be tiled. Each tile is rectangular, and has an area of 432 cm2. An exact number of tiles can be put into the space. How many tiles will be needed?

Answer 1

Step-by-step explanation:

First we need to calculate the area of the floor

Since it is a rectangulal floor, then the area to be covered is L*I= 9*3=27 m ^2

           =270,000 cm^2

Now we need to cover the area with (n) numbers of square each with 30 cm side:

Then the area of the square is 30*30=900 cm^2

Then 900*n = 270,000

==> n =300 tiles

Then we need 300 square tiles to cover the area.
