Question

Norman made a scale drawing of his patio located in the back of his house. He used the scale 1 millimeter = 2 feet. If the patio is 12 millimeters long in the drawing, how long is the actual patio?

Answer 1

Answer:

The patio is actually 24 feet long.                      

Step-by-step explanation:

Key words you need to know here are scale is 1 millimeter = 2 feet and patio is 12 millimeters long.

The question is asking how long is the actual patio, not in the scale drawing, in real life.

To solve this I'm going to set up a ratio, the scale being 1 ratio and the other ratio being 12 millimeters over blank. It's going to look like this :

$\frac{1mm}{2 ft}$ = $\frac{12mm}{x}$

To solve for x we cross multiply.

1(x) = 12(2)

x = 24

So the actual patio is 24 feet long.

Hope this helped, please mark brainliest if possible. Have a nice day! :)
