The actual length of side y is 22 cm. Use the scale drawing to find the actual length of side x.

A) 15.2 cm
B) 17.1 cm
C) 18.0 cm
D) 28.3 cm

Answer 1

D

Explanation:

by ratio n proportion, actual length of side x = 18 * 22 / 14 = 28.29 = 28.3 cm

ans is D.

Answer 2

Side Y is labeled as 1.4 cm, it is really 22 cm

To find the scale factor divide 22 by 1.2:

22 / 1.4 = 15.714

Now multiply side x by that:

1.8 * 15.714 = 28.28, round off to 28.3 cm.

The answer is D.
