Determine the side length of a square with the area of 196cm2.
Prime Factorization:
196cm2 = area
14cm = side length
Side length = Square root
Square root is the number that
multiplied itself equals the
number you are looking for.

196 divided by 14 = 14
14 x 14 = 196

Questions from the text book:

3. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. Use words and/or
diagrams to explain how you know which factor is the square root of 36.
6 is the square root of 36 because 6 is the number that multiplied by itself you get the number your looking for.

7. Determine the prime factorization for each number:

a) Not a perfect square b) Not a perfect square
c) A perfect square

12. Determine the square of each number:

The square of a number is the area.
To get the area of a square you have
to multiply side x side.
a) 3 = side
area = side x side
area = 3 x3
area = 9

b) 18 = side
area = side x side
area = 18 x 18
area = 324

14.Determine the side length for a square with an area of 900cm2.

area = side x side
area = 30 x 30
area = 900cm2
The side length of the square is 30cm2.

1. Good job Marysa! I liked the colors that you used and the pictures were nice. Next time, you should explain better, because I kind of got confused. But overall, Good Job!

2. Awesome job Marysa! I like how used color on your images and font! Next time you should organize your work a bit more, But other than that, Great job!

3. Great Job Marysa! I liked how you explained everything in pictures. Your post is very colourful. For your title you should've put your name. Other than that Good job .

4. Awsome job Marysa! I like how well you used color, unlike me, anyways. Next time i think that you should organize you pictures and your words so they look neat and organized. Other than that, good job!

5. Good job, Marysa. Your post was very colouful and showed all the answers to the questions... except one of them is wrong. 7b: 169 is a per fect square: its square root is 13. You could have also added a video. Other than that, good job.

6. Good job Marysa! I like the pictures and how its very colorful. One of you answer is wrong. #7b is wrong, like what Meldrick said 169 is a perfect square. Overall good job!
