Question

-9x^2-x+ {5x^2-(2x-4x^2)}

Answer 1

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
