Answer 4

They've represented a square in two ways.

Answer 5

OK.

Answer 6

OK, so they've made a square out of balls. (Heh.)

Answer 7

Yeah.....

Answer 8

Now what you want to see is that you can count the number of balls in two ways.

Suppose that I make you a square like that with 100 balls on one edge. What is the number of balls in that square?

Answer 9

The number is.... 1000?

Answer 10

How did you get to that number?

Answer 11

OK, so do you mean that if I place a square with \(n\) number of balls on one edge, then the number of balls is \(n^2\)?

Answer 12

Yes/

Answer 13

Alright. Now we have that with us, remove the picture and try to look at it in another way. Open the question again and notice how the square is drawn.

Answer 14

OK.

Answer 15
