 Welcome to Program 1 in our Mathematics Series from the Institute of Adat Education. Our topic today is the Pysograd Theorem. At the end of this lesson, you should be able to apply the Pysograd Theorem to solve a specified range of problems. You are welcome. Pyso, we calculate the length of your iron roof based on the dimensions of your roofing. Do you know the length and the base of your roof? Yes, I do. The height of the roof is 4 meter and the base is 6 meter. Okay, let me just make sure. Did you say the height is 4 meter and the base is 6 meter? Yes. As a matter of interest, did you do mathematics in school? Yes, but I was not very good at it because I didn't see the relevance because we seen the maths in the little life situation. But why have you asked me such a question? Welcome to the real life. Today is the day when you will see how mathematics is applied in the real life. Neither? How? You see, for us to calculate how much aluminum you need for your roof, we apply the theorem of Pysograd. Pysograd is my goodness. I have learned that in school, but I don't know how it is and how it can be applied in solving the real life problem. It works like this. By Pysograd's theorem, A squared plus B squared is equal to C squared. In our case, A stands for height. Our height and B stands for base, where C stands for length. Therefore, here we are going to put together the half of our base, this is 6 meter, 60, the square of our half and the square of our height to have the square of our length. Therefore, it means that 16 meter plus 3, 9 meter is equal to A squared. 25 is equal to A squared. In order to get the length of our sheets, it means we have square root of 25. What? I mean, can you say it again? We add up the square of the measurements of height and a half, the square of a half measurement of the base to get the square of measurement of your length. That means 4 squared plus 6 over 2 squared is equal to the square of your length. It means that 16 plus 9 is equal to the square of your length. Hence, 25 is equal to the square of your length. It means that the length of your iron sheet is square root of 25. What is the length of your iron roofing? According to your calculation, the length of iron sheet which I need is the square root of 25, which is 5 meter long. Exactly. It will be up to you, sir. Thank you, maami. And your rights. Today, I see the relationship of maxi and little life situation. I'll make sure my children do better in the class than I used to do. Thank you. Oh, our roof looks better now, my husband. I'm so glad that we can live now safely inside and even the rains can come. I'm so glad that you are very clever indeed. You have used Pythagoras theorem to solve this problem. Thank you, my husband. Oh, thank you, my wife. Now we can live in the better house. Yes. Dear viewers, this concludes the program 1 series on mathematical stage 2. Thank you for joining us. See you again next time.
