OpenStudy (kinged):

\[A(rhombus)=\frac{ pq }{ 2 }\]

OpenStudy (kinged):

p and q are the two diagonals.

OpenStudy (ellamoyseyuk):

a = (7.5)(6) / 2

OpenStudy (ellamoyseyuk):

45/2 =22.5

OpenStudy (ellamoyseyuk):

but that is not a answer

OpenStudy (ellamoyseyuk):

cause there is not 22.5 answer

OpenStudy (ellamoyseyuk):

a) 45 in^2 b) 90 in^2 c) 135 in^2 d) 180 in^2 these are one of the answer

OpenStudy (kinged):

Because you're taking half of the diagonal.

OpenStudy (kinged):

Did you notice?

OpenStudy (ellamoyseyuk):

yes

OpenStudy (kinged):

So it should be...

OpenStudy (ellamoyseyuk):

22.5 x 4 = 90

OpenStudy (ellamoyseyuk):

is that correct ?@Kinged

OpenStudy (kinged):

Yep.

OpenStudy (ellamoyseyuk):

okay thanks
