OBJECTIVE: Find the perimeter and area of rectangles, squares and parallelograms (2-9 PP73ff) ACTIVITIES: Review formulas for perimeter (Pn=s1+s2+...+sn; P=4s and P=2l+2w) and area (A=s^2; a=lw; a=bh) Review using formulas by SUBSTITUTION of values. Provide some compound shapes for analysis by groups - both for perimeter and area. NOTES: Be sure students can differentiate between perimeter and area. HOMEWORK: List the perimeters of the shapes which can have an area of 48 units square. (Dimensions must be whole units)

Canadian Soccer - to be posted October 11, 1999

I have a friend who coaches a high school soccer team in Canada. Of course I wrote to him about I Get A Kick Out Of Soccer! Here is the message he sent back:
Running laps is good conditioning, but I have my players run a "Double V" pattern instead. The Double V gives them additional practice with making quick turns while running down the field. You can see the pattern in my drawing. The players start at the southwest corner of the field, run to the top of the center line along a diagonal, then on to the southeast corner completing the first V. Next they run to the northeast corner and begin the second V. The second V takes them to the bottom of the center line and then on to the northwest corner. They finish off by sprinting back to the southwest corner.

My field has a length of 120 meters and a width of 80 meters. During each practice session the players run the Double V three times. Can you tell me how many kilometers each player runs?

This problem is a little more complicated because there are a few additional distances you need to calculate. Your explanation should include all the details of your solution. If you skip steps or just guess numbers you will not be given credit.
Bonus:
The team at my school ran 5 laps around a field measuring 75 yards by 115 yards. The team at my friend's school ran 3 Double V patterns on a field measuring 80 meters by 120 meters. Which team ran farther? State the difference between the two distances in metric units.
