CECIL'S LATEST TRICK

To amaze the audience, Cecil set up four tightropes in a rectangle, each connected at a pole as shown in the diagram at right. A ladder down from the ropes $12$ feet is located at point A.

1. If Cecil starts at point A and must travel completely around the rectangle, how far must Cecil travel?

This problem is asking you to find the perimeter (distance around) the rectangle representing the tightropes. Try finding the answer on your own before checking the answer.

$54$ feet

2. How can Cecil's distance be represented by an expression?

It is likely that the steps you did to find the answer to part (a) create an expression for Cecil's distance.

If you need more help, look back at 2-69, in which you also wrote expressions to represent Cecil's distance on tightropes.
