54 centimeters

Since you have to multiply 3 by 9 to get 27 meters, you also have to multiply 6 by 9 to get the number of centimeters, which is 54 cm. It’s a ratio problem.

6:3::x:27

x = 54

Answer:

54 cm

Step-by-step explanation:

We can use proportions to solve this problem.  Put the blue print size on the top and the real life size on the bottom.


6 cm          x cm

-----------  = -------------

3 meters   27 meter


Using cross products

6* 27 = 3 *x

Divide each side by 3

6/3 * 27 = 3x/3

54= x
