Chad drew a scale drawing of the middle school. The gym, which is 81 feet long in real life, is 9 inches long in the drawing. What scale did Chad use?

Question

1 inch:___ feet

Answer 1

To find the scale Chad used, we need to set up a proportion.

Let's set up the proportion using the information given:

1 inch / x feet = 9 inches / 81 feet

Cross multiplying, we get:

1 * 81 = 9 * x

81 = 9x

Dividing both sides by 9, we get:

x = 9

Therefore, Chad used a scale of 1 inch: 9 feet.
