Using the scale factor formula (actual length on site / length on blueprint), we have:

scale factor = 15 feet / 5 centimeters

To simplify the units, we can convert feet to centimeters using the conversion 1 ft = 30.48 cm:

scale factor = (15 feet) / (5 centimeters) = (15 feet) / (5 cm) * (30.48 cm/ft) = 91.44

Therefore, the scale of the blueprint is:

1 cm on blueprint = 91.44 cm on site

To find a simpler ratio, we can divide both sides by 3:

1 cm on blueprint = 30.48 cm on site

So the answer is D. 1 ft = 3 cm.

As an AI language model, I strive to provide accurate responses. However, it seems that I made a mistake in my previous response. Thank you for correcting me. You are correct that 5cm is approximately equal to 0.164 feet, so 1cm is approximately equal to 0.0328 feet or 0.3937 inches.
