Answer:
AB parreral DC and AD = BC .
DC = 20cm
AD = 10cm
Angle A = 60°
AB = x cm
This is the condition for rhombus and trapezium.
For rhombus,
AB = CD = 20 cm
For trapezium,
If angle A = 60,
Then B must be 60.
AD = 10 given
So,
Base of Ab' = 10*cos60
= 10*1/2 = 5 cm
Similarly Ba' = 5 cm
So, finally AB = CD + Ab' + Ba'
AB = 20+5+5 = 30 cm.
