An architectural drawing lists the scale as 1/4 = 1. if a bedroom measures 3 1/2 by 5 1/4 on the drawing, how large is the bedroom

The measure of the bedroom is 14 by 21

Step-by-step explanation:

This scale represents the every measure in the drawing is a 1/4 of the original measure, so to find the original measure you must multiply the measure you find in the drawing by 4.

So for the beadroom (3 1/2, 5 1/4), you multiply each one by 4

The real measures of the beadroom are:

(3 1/2 * 4, 5 1/4 * 4)

(14,21)

The measure of the bedroom is 14 by 21
