Math reflection

Reflection questions for the activity:

1-What is perimeter?

It is the measurement of the distance around 2D shapes 

2-Draw a picture and give an example of what perimeter is?


3-What is area?

Measurement of the surface 

4-Draw a picture and give an example of what area is?


5-How are the two related?

It is related because if you know the perimeter you know the area, and if you know the area, you can know the perimeter.
6-With a fixed (unchangeable) perimeter, describe what rectangle had the largest area? Why is that, explain your thinking?

I think if the difference between length and width is small the area is large but if the difference is big, the area is small. For example the fixed perimeter is 20, the length and width can be (1,9),(2,8),(3,7),(4,6), and the largest area is that the rectangle with (4,6) length and width which has the smallest difference between width and length.
7-With a fixed (unchangeable) area, describe which rectangle had the largest perimeter? Why is that, explain your thinking?

If it is fixed area, the difference between the width and length is big, the area is large, but if the difference between does two are small, the area is small. For example if the fixed area is 20 then, the width and length can be (1,20),(2,10),(4,5), and the largest perimeter that rectangle get is the rectangle with (1,20).
