On a blueprint the length of a wall is 5 centimeters if the actual length of the wall is 15 feet what is the scale of the blue print?

To find the scale of the blueprint, divide the actual length of the wall by the length on the blueprint. The actual length is 15 feet, which is equivalent to 180 inches (since 1 foot = 12 inches). The blueprint length is 5 centimeters, which is approximately 1.97 inches (since 1 centimeter ≈ 0.3937 inches). Therefore, the scale of the blueprint is 180 inches / 1.97 inches, which simplifies to approximately 91.4:1.
