Notes:
(copy this page and the example problem)
The perimeter of an object is the sum of the lengths of the outside edges. Circle: ! = !d Square: P = s+s+s+s or P = 4s Rectangle: P = 2l + 2w Consecutive integers: 1, 2, 3, 4, 5, 6, 7 . . . .
Consecutive Even Integers: 2, 4, 6, 8, 10, 12 . . . . . . Consecutive Odd Integers: 1, 3, 5, 7, 9 . . . . .
Problem Solving Process 1. Understand - read the problem several times and draw a diagram 2. Translate - use variables to represent your unknown values - use the information in a problem to create an equation 3. Solve - solve the equation you created in step 2 4. Interpret - determine if your answer makes sense - make sure you are answering the question that was asked Example: Find the length of a rectangular lot with a perimeter of 124 feet if the length is two more than twice the width.
