Question

56. Suppose you wish to make a scale drawing of your living room,
which measures 18 ft by 25 ft. If the shorter side of the drawing
is 6 in.. how long is the longer side of the scale drawing?

Answer 1

Answer: $8.33\ in$

Step-by-step explanation:

You know that the longer side of your living room is 25 feet and the shorter side of your living room is 18 feet.

 Then, knowing that in the scale drawing the shorter side is 6 inches, you can say that the scale factor is:

$scale\ factor=\frac{18}{6}\\\\scale\ factor=3$

Let be "x" the longer side of the scale drawing in inches.

 In order to find it, you must divide the actual longer side of you living room by the scale factor calculated above. Then you get:

$x=\frac{25}{3}\\\\x=8.33\ in$
