Question

The original blueprint for the Morenos living
room has a scale of 2 inches
5 feet, The family
wants TO use a new blueprint that shows the
length of the living room to be 15 inches. If
the width of the living room on the original
blueprint is 6 inches and the length is 9.6 inches,
what are the scale and the width of the new
blueprint?

Answer 1

Answer:

new width=9.375 in

new scale= 1 foot= 0.4 inches

Step-by-step explanation:

Firstly to find the width we can set up a proportion:

$\frac{x}{15}$ =$\frac{6}{9.6}$, after solving for x, x= 9.375, which gives us our width.

To find the new scale, we knew that the old scale was 2 in=5 feet, or 1 in=2.5 feet, so to find the new one we can also set a new proportion,

$\frac{1}{2.5} = \frac{15}{x}$

After solving you will get x= 37.5, so 15 inches= 37.5 feet, but to simplify we can divide,

15/37.5= 0.4
