Lesson 1: Count unit squares to find area

# Intro to area and unit squares

Together, we'll explore a video introducing area by comparing two figures' space on a surface. Using unit squares, we'll measure their areas, emphasizing the importance of a unit square for measuring various shapes. Created by Sal Khan.

• how does area help the real world
• I find geometry has many practical uses in everyday life, such as measuring circumference, area and volume, when you need to build or create something. Geometric shapes also play an important role in common recreational activities, such as video games, sports, quilting and food design, ect...
• how he finds the amount is by using unit square
• Using units squared will give you the answer as long as the shape you are measuring can be divided by the area of units squared. So doing this in a mathematical sense without using physical shapes, you would divide the Unit squared by the objects area. Ex. How many times would a 1cm unit go into a 3cm unit, 3 times. Because we multiplied the 1cm unit x3 to get our answer.
• I have a book that I think everyone should read. The book is called ''To Kill A Mockingbird'' and it is a great book. I think every bookworm should have a copy.
• what if you dont have UNIT SQUARES?
• What is it called when it is 4-D(example:3-D,cube units/2-D,square units)?
• There's no name for it yet...
Scientists suggest that 4 Dimensional could be time.
• how do you find the prminiter
• To find the perimeter, find the total number of units (distance) around the edges of the shape.

Have a blessed, wonderful day!
• What if the square unit is cut in half? Would it be some number .5
• Yes, you would have to think of it as 1/2 unit square.
• can i get 3 votes pls🥺
• how do find the area of a triangle?
`A = (b * h) / 2`
`A = (2 * 10) / 2 = 20 / 2 = 10`
