How it works ?
On a separate sheet of paper, solve each problem this applet generates.
As you do, be sure to
1) Draw a clear, specific, and effective model!
2) Write an equation that portrays the details of the problem.
3) Solve this equation correctly.
If you type in correct values for the length and width of the rectangle, you’ll see a big “CORRECT !!!” sign appear.
Use this applet as many times as you need in order to master this concept!
