ANSWER

We are given, that two sides of a parallelogram are 20 cm and 25 cm

Now,

Area of parallelogram = height (or Altitude) × base

here, Base QR is having altitude PT & Base SR is having altitude QU.

So, QR×PT=SR×QU

25×10=20×QU

Now, QU=x so,

x=

20

25×10

=12.5cm

So, the altitude corresponding to the other pair of sides is 12.5cm
