Question

Daniel creates a scale drawing of his room, where 12 feet = 4 inches on his drawing. If the length of one of his walls is 15 feet, how many inches long is the wall in his drawing?

Answer 1

5

Explanation:

12 feet in real life correspond to 4 inches in the drawing.

Let x represent the length of the wall in his drawing. The proportion can be set up as:

12 feet / 4 inches = 15 feet / x inches

Now, you can solve for x:

12/4 = 15/x

3 = 15/x

To isolate x, you can multiply both sides by x:

3x = 15

Now, divide both sides by 3 to solve for x:

x = 15 / 3

x = 5 inches
