I like the question, by using the word "whole" your teacher is reminding you that it takes 5 parts to make a whole side, but you only have one part. Never mind that, I'll help with your question.

Let's say you have a square that has a length of 1m, how many one meter squares do you have?|dw:1433631978841:dw|

The language is the sneaky part here, if you were to say you had one "one meter square", you would also be saying you have one squared meter. When you say one meter ($$1m$$) you're really saying one times one meter ($$1\times m$$). If you were to multiply the base times the height, or the length times the width, or the x by the y, you end up with$1m\times 1m$$1\times m\times 1\times m$$1\times 1\times m\times m$$1m^2$One meter "squared".

Make the sides 2m and tell me how many squares you have.|dw:1433632835577:dw|

$2m\times 2m$$2\times 2\times m\times m$$4m^2$

|dw:1433633185262:dw|$\frac15m\times\frac15m$Count it if you' like, you'll see it's one twenty-fifth of the squared meter. Or$\left(\frac15\right)^2m^2$
