Thank you We sneak in and here's your shmoop du

00:05

jour Brought to you by hexagons The favorite shade of

00:09

wizards and sorcerers everywhere All right kion Kion wants to

00:13

compute the area of the regular hexagon shown below Given

00:18

that line a c is equal in length The line

00:21

cd and it may be is the center of the

00:24

hex A gone she plans to use the formula area

00:28

equals blank times line a c times line c b

00:34

all right so what's this question asking Well once it's

00:36

fill in a blank to complete a formula of some

00:38

kind The formula also includes lines a c and c

00:41

b which are the two legs of the triangle So

00:44

looks like we're trying to find the area of the

00:46

triangle and then can can can just multiply that by

00:49

twelve Get the area of the entire shape they want

00:53

Well all right The area of a right triangle is

00:55

one half base times height So the area of triangle

00:58

abc this thing right here is one half times fly

01:01

Macey time's Fine B c but we have twelve of

01:03

these suckers So the area of our hexagon will be

01:06

twelve times all that stuff Well if we're taken twelve

01:09

times a half that gives us six And you know

01:12

the whole banker's doesn't think wait there we go by

01:17

dropping a six into the blank this formula will give

01:20

us the area of the hex a gun and we 00:01:23.777 --> [endTime] are theon dion with this problem Whoa
