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?
1 inch:___ feet
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.
