This site is called Studyladder. This is a site that everyone knows about because most of the school homework and school work is put on Studyladder. In this problem, I have to figure out the length of each piece of wire made from the square. The answer to this one is 9 cm. I figured this out because 4 x 9 = 36. Each length of wire is 9 cm. Studyladder is a fun site to play on. I would like to play more games like this on this site.
