Question

ABCD is a parallelogram with diagonals AC and BD intersect at O if ab is equal to centimetre and ac is 5 more than Bd find is oa​

Answer 1

Answer:

Step-by-step explanation:

∵ When diagonal AC and BD intersect each other at point o,

then OA = OC = (1/2) AC

And OB = OD = (1/2) BD

∴ OA = 1/2 × AC = 1/2 × 12 = 6 cm

and OB = 1/2 × BD = 1/2 × 9 = 4.5 cm
