# Thread: Geometry Question ( Rhombus )

1. ## Geometry Question ( Rhombus )

Hi Guys,

currently stuck with this relatively easy rhombus question.

A Rombus ABCD has an area of [5 + (7√3∕3)] cm2. Given
that the length of the diagonal AC is [ 1 + 4/3(√3)], find
the length of the diagonal BD.

Have no clue on what formula to use for rhombus at all.

Thanks !

2. Hi liukawa,

Area of rhombus= 1/2 x d1 xd2 where d1,d2 are diagonals
