Answer 1

$Hey!$

Here is your answer...

$Area \: of \: rhombus = \frac{pq}{2} \: where \: p \: and \: q \: are \: diagonals$

$Given, \\ \\ p = 12 \: cm \\ \\ area = {45 \: cm}^{2}$


$area = \frac{pq}{2} \\ 45 = \frac{12 \times q}{2} \\ 90 = 12 \times q \\ q = 7.5 \: cm$


So the length of other diagonal is 7.5 cm.

Answer 2

♠ ANSWER :

❇ One diagonal of rhombus, D 1 = 12 cm.

➤ Given, Area of rhombus = 45 cm².

➤ AREA OF RHOMBUS = 1 / 2 ( Diagonal 1, D 1 )* ( Diagonal 2, D 2 )

➤ 45 = 1 / 2 ( 12) * D2

➤ D 2 = 45 / 6

➲ 【 D 2 = 7. 5 cm. 】☑
