Answer:
The actual size of the kitchen is 1.17 feet.
Step-by-step explanation:
Given:
Blueprints of a house are drawn to the scale of 1/4=1 foot .On the blueprints, one of the kitchen walls is 3.5 in.
Now, to find the actual size of the kitchen.
Let the actual size be [tex]x.[/tex]
On the blueprints, one of the kitchen walls is 3.5 in.
Blueprints of a house are drawn to the scale of 1/4=1 foot.
1 foot = 12 in.
[tex]\frac{1}{4}=\frac{1}{4} \times 12=3\ in.[/tex]
So, 3 in is equivalent to 1 foot.
Thus, 3.5 in is equivalent to [tex]x.[/tex]
Now, to get the actual size by using cross multiplication method:
[tex]\frac{3}{1} =\frac{3.5}{x}[/tex]
By cross multiplying we get:
[tex]3x=3.5[/tex]
Dividing both sides by 3 we get:
[tex]x=1.17\ feet.[/tex]
Therefore, the actual size of the kitchen is 1.17 feet.
