00:08

the area of the square in square units using an

00:16

ancient and incredibly complex method called counting the length of

00:21

the sides on the graph What we find that this

00:24

square has sides eight units long that was really hard

00:27

to squares areas equal to the length of one side

00:29

squared So the area of the square is eight squared

00:32

equals well sixty four square units Alternatively if you wanted

00:35

to flex your two d skills and coordinate geometry well

00:39

you could have calculated the distance between two points to

00:41

find the length of one side of the square and

00:44

then looking at the top right corner we can see

00:46

that one side starts it four Comma five right there

00:49

and goes down to the point for negative Three We

00:51

don't need to worry about the distance formula since the

00:54

line is vertical and on ly the why value changes

00:57

from one point to the other The length of the

00:59

line can then be calculated in terms of the difference

01:01

between the two Why coordinates five and then subtracting the

01:05

negative three there So that gets us eight Yeah the

01:08

measurement of one side of the square gives us enough

01:10

info to find the area of square area which is

01:13

sixty for have you ever said a word so many

01:15

times it starts losing its meaning Square square Where Yeah 00:01:19.917 --> [endTime] weird
