Question

An architect's floor plan for a museum exhibit hall uses a scale of 0.5 inch : 2 feet. On this drawing, a passageway between exhibits is represented by a rectangle 2 inches wide and 3.75 inches long. What is the actual length of the passageway?

Answer 1

The actual length of the passageway is 15 feet.

Cross multiplication

To determine what is the actual length of the passageway the following calculation must be performed, through a cross multiplication:

• 0.5 = 2
• 3.75 = X
• 3.75 x 2 / 0.5 = X
• 7.50 / 0.5 = X
• 15 = X

Therefore, the actual length of the passageway is 15 feet.
