Question

In a Rhombus ABCD,AB=9cm; find its ​

Answer 1

Note: The altitude(XY) of the rhombus is $\[7\]$cm.

Given,

AB$\[ = 9\]$

XY$\[ = 7\]$

Solution,

Formula used,$\[{\rm{Area}} = {\rm{Base}} \times {\rm{Height}}\]$

Therefore, the area of the rhombus is

$\[\begin{array}{l} = 9 \times 7\\ = 63\end{array}\]$

Hence,the area of the rhombus is $\[63\]$square cm.
