Part 1: Go the Math Playground link below:
http://www.mathplayground.com/area_perimeter.html
Read through the lesson slides.
When you get to the end of the lesson, you will be given different sized rectangles and an interactive ruler tool to use. Measure the length and width of each rectangle, and calculate each rectangle's area and perimeter.
Show your work and solutions for all 10 problems on a sheet of notebook paper with your proper heading on it. Title the assignment "Math Playground Area and Perimeter Lesson".
Part 2: Solve the following puzzle.
A farmer has 40 feet of fencing to build an enclosed, rectangular pen for his animals.
a) In order to get the largest possible area to keep his animals, what would be the length and width of the animal pen he could make? (Hint: Remember, you need to use 40 feet of fence, so your perimeter would need to equal 40.)
b) What would be the dimensions of the largest rectangular pen he could make with 50 feet of fence?
c) What generalizations can you make about getting the largest possible rectangular area with a given perimeter?

Problem:
Bicycle Stunt Competition
The point totals (rounded to the nearest tenth) for the 20 participants in a bicycle stunt competition are listed
below. The rider with the highest point total out of 100 points wins.
89.4, 90, 87.5, 84.3, 89.7, 90.3, 91.4, 91, 86.7, 84.1,
89.2, 86, 89.1, 88.2, 89.5, 85.6, 90.5, 90.2, 91.1, 88.9
Use a stem-and-leaf plot to order the data. Use the following as a key:
Key: 87|5 = 87.5
Then, answer the question. How many competition participants scored more than 89 points?
