Question
Amelia drew a scale drawing of a campsite. She used the scale 9 inches : 4 feet. The tent is 8 feet wide in real life. How wide is the tent in the drawing? inches
Solution
To solve this problem, we need to set up a proportion to find the width of the tent in the drawing.
Step 1: Set up the proportion.
The scale is 9 inches (in the drawing) : 4 feet (in real life). We know that the tent is 8 feet wide in real life, and we want to find out how wide it is in the drawing (in inches).
So, we set up the proportion like this:
9 inches / 4 feet = X inches / 8 feet
Step 2: Solve the proportion.
To solve for X, we cross-multiply:
9 inches * 8 feet = 4 feet * X inches
Step 3: Simplify.
72 feet = 4X
Step 4: Solve for X.
X = 72 feet / 4 = 18 feet
However, we need the answer in inches, not feet. Since 1 foot = 12 inches, we convert 18 feet to inches:
18 feet * 12 inches/foot = 216 inches
So, the tent is 216 inches wide in the drawing.
