Terrence made a scale drawing of a boarding school. The scale he used was 7 centimeters : 5 meters. If the actual length of a building at the school is 300 meters, how long is the building in the drawing?
centimeters
To find the length of the building in the drawing, you can set up a proportion.
7 centimeters / 5 meters = x centimeters / 300 meters
Cross-multiplying, we get:
(7 centimeters)(300 meters) = (5 meters)(x centimeters)
2100 centimeters = 5x centimeters
Dividing both sides by 5, the centimeters cancel out, and we get:
2100 / 5 = x
x = 420
Therefore, the length of the building in the drawing is 420 centimeters.
