Answer 2

The actual length of the living room is 60 square feet.

Explanation:

Given:

A blueprint of a house shows a living room that is 15 square inches.

If the blueprints is 1 inch : 4 feet.

Now, to find the actual square foot of the living room space.

Let the actual square foot of the living room be
`x.`

The length of the room in the blueprint is 15 square inches.

The blueprint of the house is 1 inch : 4 feet.

So, 1 inch is equivalent to 4 feet.

Thus, 15 inches is equivalent to
`x.`

Now, to use the cross multiplication method to get the actual square foot of the living room:

`(1)/(4) =(15)/(x) \\\\By\ cross\ multiplying\ we\ get:\\\\x=60\ square\ feet.`

Therefore, the actual length of the living room is 60 square feet.
