A room is 12 feet by 16 feet. on a scale drawing the 12-foot wall is 4 inches long. how long will the 16-foot wall be?(explain how you got answer)
4/12 = x/16
so
16/3 inches
Use this proportion. Cross multiply and solve for x.
12/4 = 16/x

To find out how long the 16-foot wall will be on the scale drawing, we need to use the scale given in the problem. The scale tells us that the 12-foot wall is represented by a 4-inch segment.
We can set up a proportion to find the length of the 16-foot wall on the scale drawing. Let's consider the lengths of the walls in feet as "feet" and the lengths on the scale drawing as "inches", then we can write the proportion as:
12 feet / 16 feet = 4 inches / x inches
To solve for x, we can cross-multiply:
12 (feet) * x (inches) = 16 (feet) * 4 (inches)
12x = 64
Now, we need to isolate x, so we divide both sides of the equation by 12:
x = 64 / 12
Simplifying the fraction, we get:
x = 5.33 inches
Therefore, on the scale drawing, the 16-foot wall would be approximately 5.33 inches long.
