Answer 1

$\Large{\boxed{\underline{\overline{\mathfrak{\star \: Question :- \: \star}}}}}$

❥ The area of a rhombus whose diagonals are of lengths 10 cm and 8.2 cm is_____

$\Large{\boxed{\underline{\overline{\mathfrak{\star \: AnSweR :- \: \star}}}}}$

❥ Area of rhombus = 41 cm²

$\Large{\underline{\underline{\bf{GiVen:-}}}}$

✒ First diagonal ↠ 10 cm

✒ Second diagonal ↠ 8.2 cm

$\Large{\underline{\underline{\bf{To find :-}}}}$

❥ What is the area of rhombus ?

$\Large{\underline{\underline{\bf{SoLuTion:-}}}}$

──────⊱◈◈◈⊰──────

$\boxed {Area\;of\; Rhombus = \frac {1}{2} × d1 × d2}$

✒First diagonal ( d1 ) ↠ 10 cm

✒Second diagonal ( d2 ) ↠ 8.2 cm

Now ,

✒Putting the values in the above formula.

❥ We get;

✒ Area of rhombus ↠ ½ × 10cm × 8.2 cm

✒ Area of rhombus ↠ 5 cm × 8.2 cm

$\large{\boxed{\bold{Area\:of\:rhombus\:=\:41\:cm²}}}$
