Question

find the area of the rhombus ABCD if AC=24cm , BE=9cm and E is the midpoint of BD​

Answer 1

Step-by-step explanation:

1/2*24*9

=24/2

=12

so , 1*12*9=108

therefore , the correct answer is 108cm

Answer 2

GIVEN:-

AC=24cm

BE=9cm

E IS THE MID POINT OF BD

so, DE=BE

FIND:-

area of rhombus ABCD ?

SOLUTION:-

AC = 24 cm (given)

BD = DE + BE

BD = BE + BE (given)

BD = 9+9 cm (as BE = 9 cm)

BD = 18 cm

$area \: of \: rhombus = \frac{1}{2} \times ( d_{1} \times d_{2})$

$= \frac{1}{2} \times 24 \times 18 \\ = \frac{1}{ \cancel{2} } \times \cancel{24} \times 18 \\ = 12 \times 18 \\ = 216 {cm}^{2}$

$so \: area \: of \: rhombus \: ABCD \: is \boxed{216 {cm}^{2} }$
