Given:

  • The lengths of the diagonals of a rhombus are 24 cm and 32 cm.

To find:

  • Length of the altitude of the rhombus.

Solution:

  • We know that diagonals of rhombus bisects each other.
  • Let O be the intersecting point of both the diagonals.
  • Let AC=32 and BD= 24
  • ΔDOA Is a right angle triangle .So we can apply Pythagoras therom on this

 \therefore \: (AO) {}^{2}  + (OD) {}^{2}  = (AD) {}^{2}  \\ 16 {}^{2}  + 12 {}^{2}  = AD {}^{2}  \\ 256 + 144 = AD {}^{2}   \\ \sqrt {400}  = AD \\  Therefore \: Side(AD) = 20cm  \\  \tt \: Hence, \: The \: Side \: of \: Rhombus \\ \tt is \:  \ \underline \pink{20cm}

Given : Lengths of diagonals of a rhombus are 24cm and 32cm.

To Find : Perimeter of Rhombus ?

_________________________

Solution : Since diagonals of rhombus bisect each other at 90°, so by Pythagaras Theoram we can say that :

~

\underline{\frak{As~ we ~know ~that~:}}

  • Diagonals of a rhombus bisect each other at 90°.
  • Perimeter of Rhombus is Equal to 4 × side.
  • {\sf{\bigg( \dfrac{D_1}{2} \bigg)^{2}~ +~ \bigg( \dfrac{D_2}{2} \bigg)^{2} ~=~\bigg (side\bigg)^{2}}}

~

◗Putting D1 as 24cm and D2 as 32 cm we get :

~

\qquad{\sf:\implies{\bigg(\dfrac{24}{2}\bigg)^{2}~+~\bigg(\dfrac{32}{2}\bigg)^{2}~=~\bigg(side\bigg)^{2}}}

\qquad{\sf:\implies{12^{2}~+~16^{2}~=~\bigg(side\bigg)^{2}}}

\qquad{\sf:\implies{144~+~256~=~\bigg(side\bigg)^{2}}}

\qquad{\sf:\implies{400~=~\bigg(side\bigg)^{2}}}

\qquad{\sf:\implies{side~=~\sqrt{400}}}

\qquad:\implies{\underline{\boxed{\frak{\pink{side~=~20}}}}}

~

  • Perimeter of Rhombus = 4 × side.

~

Hence,

\therefore\underline{\sf{Perimeter~=~4~×~20~=>~\bf{\underline{80~cm}}}}
