The cost of tiles per square meter is an illustration of unit rates. If the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.
Given that:
[tex]Cost = R85.00[/tex]
The unit cost (i.e. cost of tiles per square metre) is calculated as:
[tex]Unit =\frac{Cost}{Area}[/tex]
Where:
[tex]Cost = R85.00[/tex]
[tex]Area \to[/tex] Area of the tiles
The dimension of a tile is not given. So, I will use an assumed value.
Assume the tile has an area of 17m^2.
So, the unit cost is:
[tex]Unit = \frac{85.00}{17}[/tex]
[tex]Unit = 5[/tex]
Hence, if the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.
