Question

The first part of the problem reads: Students have discovered that when they take a rectangle and double the length and width they cam predict the area of the new rectangle.

So, basically all you have to do is multiply the original rectangle's area by 4; I understood that much, but then it says:

Describe in words (like I'd describe in hand signals) *why* this relationship occurs every time we double the length and width.

What do I say?

Answer 1

Because length and width are the quantities(so to speak) of area just like length width and depth ar ethe quantities of volume.

          SO

it could be said that a change in length and width is directly proportional to the area.

e.g double the length you double the area.

Ask me if you are still stuck.
