Now on to Practise and Apply part yay ^^

6. a) Determine the prime factorization of 30. Show your work.

36=6x6

=3x2x3x2

=6x6

this is my work

b) Is 36 a perfect square? Explain your thinking.

Yes, because If you have a square of an area of 36cm square and the square had 6 on each side then yea its a perfect square.

c) Draw a quadrilateral that shows whether or not 36 is a perfect square. Label its side lengths.

7.Janie's backyard has an area of 100m2.

a) Determine the prime factorization of 100. show your work.

100=10x10
= 5x5x4

this is my work and uh sorry but i don't have a picture on this one

b) Is 100 a perfect square? Explain your thinking.
Yes, because if you have a 10x10 square on each side then it counts as 100 because its a huge square.
