Find thearea of rhombus whosediagonals area of length 10 cm and 8.2 cm​

Answer»

GIVEN: Diagonals of the RHOMBUS are of length 10CM and 8.2cm.

Need to find: Area of the rhombus.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

\underline{\bf{\dag}\frak{\;As\;we\;know\;that\;:}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

\star\;\boxed{\pink{\sf{Area\;_{(rhombus)}=\dfrac{1}{2}\times d_1\times d_2}}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

:\implies\sf{Area=\dfrac{1}{2}\times 10\times 8.2}\\\\\\\\:\implies\sf{Area=\dfrac{1}{2}\times 82}\\\\\\\\:\implies\underline{\boxed{\purple{\frak{Area=41\;cm^2}}}}{\;\bigstar}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

\therefore\;{\underline{\sf{Hence,\;the\;area\;of\;the\;rhombus\;is\;{\frak{41\;cm^2}}}.}}

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━
