Answer:
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.
