Question

Lily is starting a construction business. Her office has a length of 126.5 ft and a width of 109.7 ft. If she uses a scale factor of 1/3 for the blueprints, what will the length be?

a) 42.17 ft
b) 37.67 ft
c) 38.83 ft
d) 43.17 ft

Answer 1

To determine the length of Lily's office on the blueprint, multiply the actual length (126.5 ft) by the scale factor of 1/3 to get 42.17 ft, which corresponds to option a.

Step-by-step explanation:

To find the length of Lily's office on the blueprint using a scale factor of 1/3, you need to multiply the actual length by the scale factor. The actual length of the office is 126.5 ft. Multiplying this by the scale factor of 1/3 gives:

Length on blueprint = Actual length × Scale factor

Length on blueprint = 126.5 ft × 1/3

Length on blueprint = 42.17 ft

So the length of Lily's office on the blueprint will be 42.17 feet, option a.
