Oscar measured a theater and made a scale drawing. He used the scale 3 inches : 2 feet. If the stage is 42 inches wide in the drawing, how wide is the actual stage?
feet
To find the width of the actual stage, we need to convert the measurement from the scale drawing to actual units.
Since the scale is 3 inches : 2 feet, we can set up a proportion to find the actual width of the stage. Let x be the width in feet.
3 inches / 2 feet = 42 inches / x feet
Cross-multiplying, we get:
3 inches * x feet = 2 feet * 42 inches
3x = 84
Solving the equation, we find that x = 28 feet.
Therefore, the actual width of the stage is 28 feet.
