Best ResponseYou've already chosen the best response.2Remember that the area of a rectangle is found by multiplying the (length) x (width) of the rectangle.

Best ResponseYou've already chosen the best response.2Since the question tells us the area is 24 feet, and we want a "new banner but with same area" you just need to find the answer choice that makes an area of 24 feet.

Best ResponseYou've already chosen the best response.2lol, not very convinced I see. :) Is it the "area" part that is confusing?

Best ResponseYou've already chosen the best response.2By "area" we just mean chopping it up into 1by1 squares like this.

Best ResponseYou've already chosen the best response.2Those should all be the same size, sorry bad drawing on my part.

Best ResponseYou've already chosen the best response.2There are 2 squares per column, and 12 squares per row. That means there are 2 x 12 = 24 squares in all.

Best ResponseYou've already chosen the best response.2This is why we say that the area is (length) x (width) for rectangles. Make sense so far?

Best ResponseYou've already chosen the best response.2So, now, we want to make a new banner that has the same area (has 24 squares inside).

Best ResponseYou've already chosen the best response.2If you try B, 12 x 12 = 144 squares even worse!

Best ResponseYou've already chosen the best response.2We have no other choice but D, and in fact, 8 x 3 = 24 squares... perfect! lol
