 This video is called Area of the Shaded Region 2. There's a couple different ways to approach this problem and I know you know some students kind of tend to gravitate towards one way while many students gravitate towards another. So as the teacher who's making these videos I'm going to show you both ways. Again you don't have to understand both ways but I ask that you watch both ways and so you can kind of decide for yourself what works better for you. Some students would like to do this problem like the previous video where if you dropped lines down here you could do the area of the whole thing. Oh that got messy. Sorry I don't know why it's writing like that. You could do the area of the whole thing which is a big rectangle minus the area of the white parts. And that's a really good way to do it. You'll have your two parts. It's really easy to see the area of the whole thing. We've got eight and eight is a base and one, two, three, four. So eight times four would be thirty-two would be the area of the whole thing. And then minus the area of the white parts we would have the area of these to be four and four. So we'd have thirty-two minus eight which would give us an area of twenty-four units squared. So if you can really picture the rectangle being a piece of construction paper with those two squares cut out area of the whole minus the area of the white is a great way to go. Other students said well Mrs. Milton isn't this kind of like the problems we did at the beginning of the note sheet where you could draw an imaginary line here and an imaginary line here and find the area of all three shapes and add them up. You certainly could. Along the top it looks like it is an eight by one. Eight times one is eight. The bottom is also an eight by one. Eight times one is eight. And then in the middle if this is two and this is two that adds up to four that makes the missing part four because this bottom has to add up to eight because it matches with my top piece. Four times two is eight. So if you did eight plus eight plus eight you'd also get twenty-four units squared. Okay? So I think I'm looking at this. There's two different approaches to this problem and we've dealt with both approaches in this lesson. So it really is up to you to decide which way you want to solve this. Maybe your teacher has a preference you'll have to kind of ask him or her. Personally this is Mrs. Milton. I like both ways as long as you can show your work so I can see your thinking I would accept either method. You choose what you like the best and go with it. All right? So it's time to work on your checking quiz please. Make a solid effort. Take your time. Answer the questions really the best you can. Don't just fly through it and we will work on all of this more in class tomorrow. Thanks. Have a good night.
