00:21

formulas for the area of the rhombus But we want

00:23

to use the one that wasn't late for lunch Since

00:26

we're given the length of one of the diagonals We

00:28

want the area formula that uses a rhombus diagonals in

00:31

that way we can substitute in our own known values

00:34

and find the value of the unknown diagonal right So

00:37

that area formula is area is one half d one

00:41

in times day to there find the missing diagon all

00:43

through substitution You know each diagonal angle one day going

square meters is one half times eighteen meters times diagonal

00:54

too and well we can just bang that out to

00:56

be nine Divide out both sides by nine we get
