Answer 1

Hi Ngan from San Francisco, CA...hope you had a great day at school.

Okay...great question...I've use this before with my students.

Now...I'm going to give you two hints to solve this, but I won't answer it for you, because once you learn how to answer these kinds of questions, you'll be a pro. Giving the answer to you would be too easy.

Hint...from the first part of the word problem: "A square'...which should tell you that the definition of the polygon is that each of the sides of the figure are ALL EQUAL!

Second hint of the word problem: "...the area of the square is 67cm²

Third hint...which you should know, what is the formula for calculating the area of a polygon, in this case a square:

             side x side = area of polygon  

and since this is a square, all the sides are equal...so we'll say:

                  s cm  x  s cm   =  67cm²

Since we multiply both sides, both equal we can write:

                   s² cm   = 67cm²

So...what would you do to find out what      s  =  ?cm

You should be able to do this, I've given you enough hints.
