Answer:
The actual length of the living room is 60 square feet.
Step-by-step 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 [tex]x.[/tex]
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 [tex]x.[/tex]
Now, to use the cross multiplication method to get the actual square foot of the living room:
[tex]\frac{1}{4} =\frac{15}{x} \\\\By\ cross\ multiplying\ we\ get:\\\\x=60\ square\ feet.[/tex]
Therefore, the actual length of the living room is 60 square feet.
