Kirk made a scale drawing of the elementary school. The scale of the drawing was 3 millimeters : 4 meters. If the actual width of the schoolyard is 60 meters, how wide is the schoolyard in the drawing?

Question

millimeters

Answer 1

To find the width of the schoolyard in the drawing, we can set up a proportion using the scale of the drawing.

Let "x" represent the width of the schoolyard in the drawing.

According to the scale, we have:

3 millimeters : 4 meters = x millimeters : 60 meters

To find "x", we can cross multiply:

(3 millimeters)(60 meters) = (4 meters)(x millimeters)

180 millimeters * meters = 4x millimeters * meters

180 = 4x

x = 180/4

x = 45

Therefore, the width of the schoolyard in the drawing is 45 millimeters.
