Given:
Model tile length =

Model tile width =

Actual tile length =

Actual tile width =

To find:
The ratio of the length of a tile in the model to the length of an actual tile and the ratio of the area of a tile the model to the area of an actual tile.
Solution:
We know that,
1 ft = 12 in.
Actual tile length


Actual tile width



The ratio of the length of a tile in the model to the length of an actual tile is

Therefore, the ratio of the length of a tile in the model to the length of an actual tile is
or it can be written as 1:9.
Area of rectangle = length Ă— width
Area of model tile


Area of actual tile


The ratio of the area of a tile the model to the area of an actual tile is



Therefore, ratio of the area of a tile the model to the area of an actual tile is
or it can be written as 1:81.
