We broke it up into two hundreds, two hundreds right over here. This kind of a rectangle, breaking it up into chunks that are, maybe easier to imagine dividing by two. We just did over here, but we visualized it using You say, "Look, two hundredsĭivided by two is 100, "six tens divided by two is three tens, "eight ones divided by two is four ones." And that's exactly what And so this whole length up here is going to be 100, plus 30, plus four, or 134. Is 200, 30 times two is 60, four times two is eight. This section going to be? It's going to be, it's going to be, eight divided by two, which is four. So this part of the field is going to be 30 in that direction and two in this direction. What's 60 divided by two? Well, 60 divided by two is going to be 30. And how did we get that? Well we got that by 200 divided by two. Going to be a hundred, so this is going to be 100. Right over here going to be? Well two times that is To be, right over here? Actually let me do that So what is, what is this, what is this dimension going I can take each of them and divide by two. Now I can take those things and divide by two. Into things that are easier to divide by two, and "plus 60, plus eight." I just broke up the 268 All I did is I took the 268, and I said, "Well look, this is the same thing as "200 plus 60. Now why is that useful? Well, now each of these, it's So this blue area is 200 units, this yellow area is 60 units, and this magenta area is eight units. Here is still two units, two units, but I've broken it up. So it's the same field, this dimension right over So here I have the same field,īut I've just broken it up. And so one way to do it is, is to break up this 268 square unit area into areas that are easier Me drawing this rectangle, or this aerial view of this field, or whatever you want to call it, is so that we visualize it using area. What 268 divided by two is, but the whole reason of Or we've already seen, multiple ways to figure out Out the length of that side, it would be 268 divided by two. Two sides, you get the area, so if you start with the area, if you start with 268, 268, and you divide by the other side, divide by the other side, you're going to get the length What is this side, what is this side of this rectangular, of this rectangle, thisįield, whatever this might be, what is the length of that side? Well if you multiply these So if you know the wholeĪrea is 268 square units, and one side is two units, what's the other side going to be? What is the other side going to be? What is, what is. Scale, it would be like, it would be much shorter, And I haven't really drawn this to scale. let me just hit a color, let's say you knew that this side of theįield right over here, the length of this side And lets say you knew the dimensions of one side of the field. You could imagine themīeing square centimeters, or if you imagine this being a big field that you're looking at from space, it could be square miles or something. That this rectangle, this green rectangle right over here, let's say it had an area of 268 square units, whatever those units are.
