Luna measured the elementary school and made a scale drawing. The schoolyard, which is 175 meters long in real life, is 25 centimeters long in the drawing. What scale did Luna use for the drawing?
To find the scale, we need to compare the lengths in the drawing to the lengths in real life.
In the drawing, the schoolyard is 25 centimeters long. In real life, the schoolyard is 175 meters long.
The scale can be found by dividing the length in real life by the length in the drawing:
Scale = Length in real life / Length in the drawing
Scale = 175 meters / 25 centimeters
To calculate this, we need to convert the units to be consistent.
1 meter = 100 centimeters, so 175 meters = 175 * 100 = 17500 centimeters.
Scale = 17500 centimeters / 25 centimeters
Scale = 700
Therefore, Luna used a scale of 1:700 for the drawing.
