Question

two sides of parallelogram are 20 cm and 25 CM if the altitude corresponding to the sides of length 25 cm is 10 centimetre find the altitude corresponding to the other pairs of side ​

Answer 1

Ansr:We form our diagram from given information :

Here , Altitudcorresponding to side ( AB = 25 cm ) = DM = 10 cm and

Altitude corresponding to side ( BC = 20 cm ) = AN = x cm ,

We know area of parallelogram = Base × Height ( Or Altitude )

Then,

Area of given parallelogram ( We consider base = AB = 25 and Altitude = DM = 10 cm ) = 25 × 10 = 250 cm2

And

Area of given parallelogram ( We consider base = BC = 20 and Altitude = AN = x cm ) = 20 × x = 20x cm2

So,

20 x = 250 ,

x = 12.5

Therefore,The altitude corresponding to the pair of sides = 12.cm ( Ans )

Hope it helped you.
