  2. AREA AND PERIMETER OF RECTANGLES LESSON In this lesson you will be learning about how to find the area and perimeter of a rectangle! Please be sure to quietly work on this assignment individually. There will be a quiz at the end, so pay attention and make sure you understand everything! Don’t be afraid to go back to previous slides if you aren’t sure of a concept. Have fun!

  3. INTRODUCTION QUIZ CLICK PLAY ON THE SOUND BUTTON BELOW IF YOU AREN’T SURE WHAT TO DO AREA PERIMETER SCAVENGER HUNT

  4. Here’s a cool video from NASA!

  5. Perimeter • Perimeter = 2L + 2W • Perimeter is the distance around a two-dimensional shape

  6. Perimeter = 2L + 2W 2(4) + 2(10) = 8 + 20 = 28 feet

  7. Area • Area = L x W • Area is the size of a surface

  8. Area = L x H 10 x 4 = 40 feet

  9. Are you ready for the Scavenger Hunt? • In the next few slides, click on the image that has the correct height or width that you are looking for.
