You can put this solution on YOUR website! To solve, we need to set this problem up as a proportion. The picture is originally 3 by 5, so  . It's enlarged to something by 6 feet. In other words,  , where x is our unknown. In proportional form, this would look like
To solve this proportion, cross multiply, and place the results on each side of the equal sign:
6*3 = 5*x
18 = 5x
Divide both sides by 5, to get x by itself. This gives us
In decimal form, this equals 3.6
So, the length of the shorter side is 3.6 feet
