Remember that the area of a rectangle is found by multiplying the (length) x (width) of the rectangle.

bc 8 x 3 = 24

Since 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.

lol, not very convinced I see. :) Is it the "area" part that is confusing?
anonymous
  • anonymous

OH

By "area" we just mean chopping it up into 1-by-1 squares like this.

Those should all be the same size, sorry bad drawing on my part.

There are 2 squares per column, and 12 squares per row. That means there are 2 x 12 = 24 squares in all.

its ok

This is why we say that the area is (length) x (width) for rectangles. Make sense so far?
anonymous
  • anonymous
yep
jtvatsim
  • jtvatsim
So, now, we want to make a new banner that has the same area (has 24 squares inside).

ok

Well, look at choice A, a 20 by 4 banner... WAY TOO BIG!|dw:1434057484750:dw|

If you try B, 12 x 12 = 144 squares even worse!

its d

C, is no good either, 6 x 3 = 18 squares... too small!

We have no other choice but D, and in fact, 8 x 3 = 24 squares... perfect! lol

That clear things up?
