Area and Perimeter of Shapes

The video tutorial explains the relationship between area and perimeter, focusing on how to calculate one when given the other. It starts with a square, using its perimeter to find the area, and then moves on to a rectangle, using its area to determine the perimeter. The tutorial provides step-by-step instructions and examples to help fourth-grade students understand these concepts.

What is the relationship between area and perimeter?

• They are unrelated.

• Area is always larger than perimeter.

• Area and perimeter are the same.

• Perimeter can be used to find area in some shapes.

How do you find the area of a square if you know its perimeter?

• Divide the perimeter by 4 and square the result.

• Subtract 4 from the perimeter.
