The following figures above all have the same area, but may have different perimeters. Which of the figures has the smallest perimeter?
Describe the difference between AREA and PERIMETER of a given shape.

2. Page 31 How many sides make up the perimeter of the triangle?
How many sides make up the perimeter of the square?

3. (2x) + (2x) + (x – 8) (x + 2) + (x + 2) + (x + 2) + (x + 2) Page 31
Write an expression for the perimeter of the triangle.
Write an expression for the perimeter of the square.
(2x) + (2x) + (x – 8)
Note: There are multiple ways that you can write the equations without changing their meaning.
(x + 2) + (x + 2) + (x + 2) + (x + 2)

4. 5x – 8 4(x+2)  4x + 8 Page 31 (2x) + (2x) + (x – 8)
Simplify your expression:
(2x) + (2x) + (x – 8)
5x – 8
(x + 2) + (x + 2) + (x + 2) + (x + 2)
4(x+2)  4x + 8
