- What's area and perimeter?
- Area and Perimeter are how big the inside of an object is and how big the outside of an object is. To find the area, you must multiply the length and the width of the object. To find the perimeter of an object, you need to add all of the sides together. I hope you understood the concept of Area and perimeter.
