Perimeter and Area Formulas

[@barfield02]

thanks this was very helpful. the fact that you grouped all the areas together was completely helpful cause i didnt have to go in find another video it was all in one.

Thank you... Now i can memorize the formulas for perimeter...

[@anonymouss1270]

No way my math professor linked a lesson that he didn't make. I hope you can teach me well, Mathispower4u, my real professor, apparently.

I do my best. :) I have been creating and posting videos for 15 years! I didn't realize it had been so long.

[@anonymouss1270]

@@Mathispower4u And you are still answering comments all these years later. If you would be so kind I have a question. For the area of a triangle I got 40ft^2 because I thought you were meant to divide by 2, do you not divide by 2?

[@Mathispower4u]

@@anonymouss1270 Yes, I have an example at 4:55. The formula is 1/2bh or (bh)/2. For my example, we have (20*8)/2=80 square feet. kzbin.info/www/bejne/kHK2c6ClrtF2hsUsi=9qKAqa2UPO73isPU&t=295

how do i get the link without switching from tab to tab coppying every letter/number??

[@Mathispower4u]

I have many short videos with the graph paper background. The yellow background videos are longer mini-lessons. Thanks for the comment.

I'm not good in math but how do you get 3? in 1/2 . 6?

[@jaibee17]

The answer is 3 because multiplying a number by 1/2 is the same as dividing that number by 2. 6÷2=3
