Question

Mrs. Rodriguez has a blueprint of her new house. The actual living room has a width of 20 feet and a length of 24 feet. If the scale
used to make the blueprint is inch = 4 feet, what is the length of the living room on the blueprint?
12 inches
3 inches
5inches
6 inches

Answer 1

Answer:

D) 6 in

Step-by-step explanation:

The length is 24 feet. The blueprint scales 1 ft : ¹/₄ in.

So, we can set up a proportion: 1 ft / ¹/₄ in = 24 ft / x in

Cross-multiply: 24 * ¹/₄ = x

Multiply: x = 6 in
