Answer 1

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 $x.$

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.

$\frac{1}{4}=\frac{1}{4} \times 12=3\ in.$

So, 3 in is equivalent to 1 foot.

Thus, 3.5 in is equivalent to $x.$

Now, to get the actual size by using cross multiplication method:

$\frac{3}{1} =\frac{3.5}{x}$

By cross multiplying we get:

$3x=3.5$

Dividing both sides by 3 we get:

$x=1.17\ feet.$

Therefore, the actual size of the kitchen is 1.17 feet.
