Question

Becky drew a scale drawing of a house. In real life, the garage is 9 meters long. It is 18 centimeters long in the drawing. What scale did Becky use for the drawing of the garage?

a) 1:500
b) 1:50
c) 1:1000
d) 1:2000

Answer 1

Becky used a scale of 1:50 for the drawing of the garage.

Step-by-step explanation:

To find the scale that Becky used for the drawing of the garage, we need to compare the length of the garage in the drawing to its actual length. The garage is 18 centimeters long in the drawing and 9 meters long in real life.

Since 1 meter is equal to 100 centimeters, the length of the drawing in meters is 18/100 = 0.18 meters.

Now we can find the scale factor by dividing the actual length by the length in the drawing: 9 meters / 0.18 meters = 50.

Therefore, the scale that Becky used for the drawing of the garage is 1:50.
