Question

In a parallelogram ABCD, AB= 25 cm and the corresponding altitude is 15 CM. if the area of parallelogram ABCD is equal to the area of another parallelogram PQRS with side QR= 20 CM, then find the altitude of this parallelogram corresponding to side QR.

Answer 1

From the given data



We can understood


both have same are

consider x,the altitude of PQRS

then

there areas can be equalise like

25×15=20×x


from above equation x =18.75cm



Thank You to Ask..

Answer 2

Let the altitude be x

25×15 =20 × x

375 =20 × x

375 /20 = x

18. 75 = x

Altitude = 18.75 i. e. x
