Answer 1

area is l times w so find out which one multiplied equal 24

Answer 2

wut * pocker face *

Answer 3

it would be d

Answer 4

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

Answer 5

bc 8 x 3 = 24

Answer 6

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.

Answer 7

yep @jtvatsim

Answer 8

uh huh...

Answer 9

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

Answer 10

yep :D

Answer 11

OK, so I guess you could draw a picture and think of it this way...

Answer 12

Here's the old rectangular banner.

Answer 13

OH

Answer 14

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

Answer 15

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

Answer 16

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

Answer 17

its ok

Answer 18

This is why we say that the area is (length) x (width) for rectangles. Make sense so far?

Answer 19

yep

Answer 20

So, now, we want to make a new banner that has the same area (has 24 squares inside).
