Kirk measured a petting zoo and made a scale drawing. The scale he used was 7 centimeters : 6 meters. If the actual length of the goat pen is 18 meters, how long is the pen in the drawing?

Question

centimeters

Answer 1

To find out the length of the pen in the drawing, we can set up a proportion with the given scale.

Let's say x represents the length of the pen in the drawing.

According to the scale, 7 centimeters corresponds to 6 meters.

Therefore, we can set up the proportion:

7 centimeters / 6 meters = x centimeters / 18 meters

Cross-multiplying, we get:

7 centimeters * 18 meters = 6 meters * x centimeters

126 centimeters * meters = 6x centimeters * meters

Canceling out the units, we have:

126 = 6x

Dividing both sides by 6, we get:

x = 126 / 6

x = 21

Therefore, the length of the pen in the drawing is 21 centimeters.
