Each tile has length 1/3 in. And width 1/4 in. The actual tiles have length 1/4 ft and width of 3/16 ft. What is the ratio of the length of a tile in the model to the lenfth of an actual tile? What is the ratio of the area of a tile the model to the area of an actual tile? Describe two ways to find each ratio

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 × 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.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
