  1. Algebraic expression through finding area and perimeter of Geometric shapes. Objective G705: The student will solve multi-step geometry problems that involve integrating concepts, planning, and/or visualization.

  2. Reminders: • Area of a quadrilateral is base times height (same thing as length times width. • Area of a triangle is ½ base times height. • Perimeter is the sum of all sides. • Ex. 1: Susan plans to construct a shed for her garden. It will have a square-shaped floor. Each side is represented by the expression (9x + 3) feet. Determine the expression that represents the area of the storage building?

  3. Ex 2: Janet’s bedroom is represented the picture below. What would the perimeter of her bedroom be if she increased the length and width by 5? 5x – 3 X + 1

  4. 11. Write an expression represents the area of the triangle below? 4x 7x – 2

  5. The dimensions of a room are: (8x + 1) by (x - 4) when measured in feet. a. Write an expression that represents the area of the room? b. Write an expression that represents the perimeter of the room?
