Final answer:
Omar used a scale of 1 centimeter representing 75 centimeters, or 1:75.
Step-by-step explanation:
To find the scale that Omar used for the drawing, we need to determine the ratio of the actual width to the width in the drawing. In this case, the actual width of the sand volleyball court is 9 meters and the width in the drawing is 12 centimeters. We can set up the following proportion:
9 meters / x = 12 centimeters / 1
To solve for x, we can cross multiply and then divide:
x = (9 meters imes 1) / 12 centimeters
Converting meters to centimeters, we get:
x = (900 centimeters) / 12 centimeters
Simplifying the expression gives us:
x = 75
Therefore, Omar used a scale of 1 centimeter representing 75 centimeters, or 1:75.
