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.

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.
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!
