Answer :
Given, a parallelogram of which adjacent sides are 25 cm and 15 cm and length of one diagonal is 20 cm.
Consider a parallelogram ABCD, adjacent sides are given, AB=25cm
BC=15cm
And diagonal AC=20cm
Semi perimeter of ∆ABC, S =
S = 30cm
Hence area of ∆ABC = sq. cm
Area ∆ABC = 150 sq. cm
Area of parallelogram ABCD = 2×area of ∆ABC
Area of parallelogram ABCD = 2×150
= 300sq. cm
Let, Height AE = h
Area of parallelogram ABCD= base × height
⟹ 300 = 25 × h
⟹ h =
⟹ h = 12cm
