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?
millimeters
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.
