Step-by-step explanation:
In rhombus ABCD,
16 cm
12 cm
B
I(AC) = 16 cm and I(BD) = 12cn . Let the diagonals of rhombus ABCD intersect at point O.
l(AO)=(1/2)l(AC)... [Diagonals of a rhombus
bisect each other]
.. l(AO) = (1/2) * 16
.. I(AO) = 8 cm
Also, mathcal l (DO)=(1/2) mathcal l (BD) ... [Diagonals of a rhombus bisect each other]
.. l(DO) = (1/2) * 12
.. I(DO) = 6 cm
