An architect is building a model of a tennis court for a new client. On the model, the court is 6 inches wide and 13 inches long. An official tennis court is 36 feet wide. What is the length of a tennis court?

Answer 1

The court is #78# feet long

We can make a ratio out of this problem. We know that #6# and #36# are proportional to eachother, which gives us #6/36=13/l#. To solve for #l#, we just simplfy #6/36# to #1/6#. That gives us #1/6=13/l#. Now we just multiply both sides by #6#, which looks like this #cancel(6)*1/cancel(6)=13/l*6#. If we multiply both sides by #l#, we get #l=78#.
