In this video, I show how to recognize and use units of area. I teach how to calculate the area of a rectangle by counting square units and using the side dimensions. I present the units of area from square millimeter to square kilometer, explain how to multiply length by width to find the area, and analyze exercises with real, schematic, and dimensioned drawings. I also explain the importance of converting units to the same type before performing calculations. TABLE OF CONTENTS: 1. Units of area: square millimeter, square centimeter, square decimeter, square meter, square kilometer 2. Calculating the area of a rectangle by counting units 3. General formula for the area of a rectangle 4. Example with a drawing in centimeters 5. Example with a drawing in millimeters 6. Example with a schematic drawing in decimeters 7.
