Gabriel measured a house and made a scale drawing. The garage, which is 12 meters long in real life, is 4 millimeters long in the drawing. What scale did Gabriel use for the drawing?
1 millimeter : meters
To find the scale, divide the length of the garage in real life by the length of the garage in the drawing:
12 meters / 4 millimeters = <<12/4=3>>3 millimeters per meter
Therefore, Gabriel used a scale of 1 millimeter per 3 meters for the drawing.
What’s the answer
The answer is that Gabriel used a scale of 1 millimeter per 3 meters for the drawing.
To determine the scale used by Gabriel for the drawing, we need to find the ratio of the length on the drawing to the actual length.
Let's denote the scale as "1 millimeter : X meters".
We are given that the length of the garage in the drawing is 4 millimeters and the actual length of the garage is 12 meters.
Setting up a ratio with the lengths, we have:
4 millimeters / 12 meters = 1 millimeter / X meters
Cross multiplying, we get:
4X = 12
Dividing both sides by 4, we have:
X = 12 / 4
X = 3
Therefore, Gabriel used a scale of "1 millimeter : 3 meters" for the drawing.
