What is the perimeter of this shape?
You would do 5 + 5 + 3 + 3.
This equals 16cm! Try not to forget the labels even though Mr. T does sometimes.

If this is KoKo's frozen peanut butter treat, how many square centimeters of peanut butter does she get?
Well, you would need to multiply 3 times 5...
So, 3 x 5 = 15 square cm of peanut butter
What is the area of this square?
The area would be 6 x 6 = 36 sq m.
Which shape has 4 equal sides and may have NO right angles?

What is the perimeter of the following figure?
The perimeter would go as follows:
4 + 3 + 3 + 2 + 2 + 6 + 1 + 1 = 22 units!
Draw another shape that "Fits the Rule."
What do you think the rule is?
The rule is: "It must be a rectangle."
All three shapes are quadrilaterals and parallelograms, but the two shapes that fit the rule are both rectangles (they have four right angles.)
Name this shape with as many names as possible. You need AT LEAST THREE names.
1.) Polygon
2.) Quadrilateral
3.) Parallelogram
4.) Rectangle
The perimeter is 30 ft. What is the length of the missing side?

What is the area of the figure below?
Well, if you break it up into three rectangles, they would look like this:
So, you would have:
4 x 2 = 8, 3 x 3 = 9, and 3 x 9 = 27
8 + 9 + 27=44 sq cm!
What is the perimeter AND the area for the following parallelogram?
Well, the perimeter would be 8 + 8 + 4 + 4 = 24 m.
The area would be 4 x 8 = 32 sq m.
