Here's your shmoopy question du jour...

00:06

The drawing of a tree has a scale of 1 cm = 4 ft as shown below. 

00:12

What is the actual height of the tree in feet?

00:17

Here are the potential answers...

00:22

This question is a standard conversion question -- can we translate centimeters into American?

00:29

Er... uh... feet.

00:32

Since the answers are all in feet, we don't care about inches...

00:35

...but that could be a curveball these test making people throw your way.

00:39

So... we're told that 1 centimeter equals 4 feet -- which sets up a ratio.

00:46

1 is to 4 as 6.75 is to... what?

00:52

Well, just multiply 6.75 by 4 and we get the answer: 27.

01:02

So it's D.
