I WILL MARK BRAINLIEST!!!!!!!!!

A scale drawing of a building is one foot to 1/4 inch. What is the actual length of the building if the scale drawing shows that it is 13 1/2 inches long?

Answer 1

Answer:

54 ft

Step-by-step explanation:

1 ft               x ft

------------- = ------------

1/4 in           13 1/2 inch

using cross products

1 * 13 1/2 = 1/4 * x

13 1/2 = 1/4 x

times by 4 on each side

4* 13  1/2 = x

change 13 1/2 to and improper fraction ( 13 1/2 = (2*13 +1)/2 = 27/2)

4 * 27/2 =x

54 =x
