Question

7. Find the area of a rhombus whose diagonals are of lengths 15 cm and 25 cm​

Answer 1

Answer:

the formula for the area of a rhombus is

1/2*diagonal1*diagonal2

so, according to the formula and the question,

1/2*15*25 =375/2

=187.5 cm^2

Answer 2

$\large \bold{ \underline{ \underline{ \sf \: Answer : \: \: \: }}}$

$\to$ Area of rhombus = 18.75 cm

$\large \bold{ \underline{ \underline{ \sf \: Explaination : \: \: \: }}}$

Given ,

Length of 1st diagonal (D1) = 15 cm

Length of 2nd diagonal (D2) = 25 cm

$\bold{ \fbox{ \fbox{ \sf \: Area \: of \: rhombus = \frac{D1 \: × \: D2}{2} \: \: }}}$

$\to \sf Area \: of \: rhombus = \frac{15 × 25}{2} \\ \\ \to \sf Area \: of \: rhombus = \frac{375}{2} \\ \\ \to \sf Area \: of \: rhombus = 20 \: cm$

Hence , the required value is 18.75 cm
