1. Area and Perimeter By: Julia Lopez

2. Perimeter of a Square The formula of a square to find the perimeter of a square is: S+S+S+S 4 4 4 4 P= S+S+S+S P=4+4+4+4 P= 16

3. Area of a Square The formula of a square to find the area of a square is: B times H 4 A= B times H A= 4 times 4 A= 16 4

4. Perimeter of a Rectangle The formula for a rectangle to find the perimeter is : S+S+S+S 5 7 7 5 P= S+S+S+S P= 7+5+7+5 P= 24

5. Area of a Rectangle The formula to find the area of a rectangle is : B times H 5 8 A= B times H A= 8 times 5 A= 40

6. Perimeter of a Triangle The formula of a triangle to find the perimeter is : S+S+S 6 6 4 P= S+S+S P= 6+6+4 P= 16

7. Area of a Triangle The formula to find the area of a triangle is B times H divided by 2 4 4 2 6 A= B times H divided by 2 A= 2 times 6 divided by 2 A= 6

8. Area of a Irregular Shape If you come across a shape that has two or more different shapes in it you would have to area of one shape then the next one. 5 5 5 4 3 2 2 First you would do the square. Then you would do the triangle. Then you would add them both up by there area. A= B times H A= B times H /2 A= 5 times 5 A= 5 times 2/2 A= 25 A= 5
