I'm going to surround it by a fence on all sides, with a next-door neighbor who has a rectangular plot the same size and dimensions. It looks just like mine, and it's right next door to mine.

If you don't know what you're solving, you can't solve it.

So I'm going to highlight 'what percentage of his fence have you completed for him already.' The second big key is to draw it out. I'm going to draw out a square plot of land and call it mine.

Everybody knows that's a rectangle - it's just a particular type of rectangle. We have a square plot, a fence on all sides, a next-door neighbor, and the same size and dimensions.

I'm also going to say that the ending question is really important.

Practice translating complex problems into simple, meaningful images in this lesson.

Let's stop and take a minute to think about how important visualization is to everything in everyday life. I'm reading a book right now about how they're trying to find astronauts to go up to Mars, and one of the things they have astronauts do is make a thousand cranes. They take a sheet of paper, they follow two pages of instructions and they make a crane. I don't know about you, but when I try to make a crane I end up with an airplane - a paper airplane - and it never flies particularly well either. Well, it's because I don't follow these keys to understanding visualization problems from a sheet of paper. The first key is that you need to pull out the most important information.This edge here is going to join this edge here, along one edge. So now I have a box that's 3 centimeters by 6 centimeters by 1 centimeter. What's more, we actually took a sheet of paper and folded it up to see. One, you want to pull out all of the important information.Then I'm going to get a new edge where these two edges meet. I'm not quite sure that this is going to work, so let's pull out a sheet of paper and actually do this. The width is going to be, now, 6 centimeters because we had 8 centimeters and we took off 1 on each side. The height from my sheet of paper is going to become the depth of the box, and that's now 3 centimeters, because we've folded up the front and the back. If you know how to find the volume of a box, then you would know that the whole volume of this is going to be 1 * 3 * 6. And when you're done with the problem, you need to look at that important information and make sure that your solution satisfied all of those bits. You know at the end, you need to have a head on your origami crane.What is the equation of the line in slope-intercept form?As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.What percentage of his fence have I already completed for him? He needs to surround his plot of land on all four sides with a fence, but one of those sides is adjacent to my plot. This means that one side of his fence is done and he needs three sides.What percentage of the fence have I completed for him? We are given a paper rectangle of area 40 centimeters squared that has a width of 8 centimeters and a height of 5 centimeters (well, yes, a width of 8 centimeters and height of 5 centimeters will give me 40 centimeters squared, so I'm good.) I'm going to cut 1-centimeter squares from each of the four corners. I'm going to cut 1-centimeter squares from each corner.Need some help figuring out how to work with angles in geometry? From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts.And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).In a different color, I'm going to put his fence, or what he would like around his entire plot.I've drawn it out, and now I just need to solve it.
