Lesson 2: Perimeter and Area

# Perimeter & area

Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy. Created by Sal Khan.

• How would I use multiplication instead of addition to find the perimeter?
• will tell you
• If you add each side, then is the total your area or (base x height)?
• When you add each side you get the perimeter.
When you multiply the base times height you get area.
For a 3-D figure you find the area of the base, then multiply it by the height, and you get the volume.
• How much is a right angle
• 90 degrees , you can tell a right angle because of the small box in the triangle
• what is the easyiest way to know all of this? im like so confused?
• Area=multiply base x height
Hope this helps! :)
• How do you find the area and perimeter of a square if it's sides are in a fraction.
• You would continue the same way you would if they were whole numbers. Multiple or add them depending on whether you are finding area or perimeter.
• what is the difference between the perimeter and area?
• Perimeter is the distance around the shape.
Area is the space inside the shape.
• Could I use division in perimeter and area
• In perimeter, no. In area, you would have to take the reciprocals of the two sides given and divide them as fractions, but that would be an extra step. So, basically, no :)
• How do you find area?
• for finding area you have to multiply the length and width
