Alaina measured a boarding school and made a scale drawing. The scale of the drawing was 1 millimeter = 7 meters. In the drawing, a building at the school is 16 millimeters long. What is the length of the actual building?

The length of the actual building is 112 meters long.

Step-by-step explanation:

The key words we need to know are these : scale is 1 millimeter = 7 meters, and 16 millimeters long.

The question is asking for the building's actual height.

To solve this, we need to set up a ratio, have the scale being one ratio and the other 16 millimeters over blank. It's going to look like this :

=

We need to make sure all the units are lined up - the mm parts of the ratio are next to each other.

Now that we have our ratio set up we can cross product to solve for x.

1(x) = 16(7)

x = 112

So x is 112, or the length of the actual building is 112 meters long.

Hope this helps, please mark brainliest if possible. Have a nice day. :)
