Answer:

The length of the actual bathroom wall in inches is 96 inches.

And the length of the actual bathroom wall in feet is 8 feet.

Step-by-step explanation:

Given:

A scale drawing has a bathroom wall that is 8 inches long.

The scale factor is [tex]\frac{1}{12}[/tex] .

Now, to find the length of the actual bathroom wall in inches and in feet.

Let the actual length of the bathroom wall be [tex]x.[/tex]

The length of wall in scale drawing =  8 inches.

As, the scale factor is [tex]\frac{1}{12}.[/tex]

So, 1 is equivalent to 12.

Thus, 8 is equivalent to [tex]x.[/tex]

Now, to solve using cross multiplication method:

[tex]\frac{1}{12} =\frac{8}{x}[/tex]

By cross multiplying we get:

[tex]x=96\ inches.[/tex]

The actual length of the bathroom wall is 96 inches.

Now, to get the actual length of bathroom wall in feet we use conversion factor:

1 inch = [tex]\frac{1}{12} \ foot[/tex] .

96 inches = [tex]\frac{96}{12}\ feet.[/tex]

96 inches = 8 feet.

Thus, the actual length of bathroom wall in feet is 8 feet.

Hence, the length of the actual bathroom wall in inches is 96 inches.

And the length of the actual bathroom wall in feet is 8 feet.
