Question

Find the area of rhombus ABCD given that AB=9cm and altitude DO=7cm.

Answer 1

Since all the sides are equal of rhombus and it is also a parallelogram .
It's area = base × altitude
area = 9 × 7 sq.cm
area = 63 sq.cm

Answer 2

Given,

AB$\[ = 9\]$

DO$\[ = 7\]$

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.
