See The Parallel Sides Are 20cm And 10 cm.
So Longer Side Differs From the shorter side by 20-10 = 10 cm
Or 10/2 = 5 cm
Hence On Each Side THE LONGER SIDE HAS 5 cm Extra
It Will Act As Base
Hypoteneuse = Non Parallel Sides
Height ^2= 13^2-5^2
Height ^2 = 144
Height = 12cm
Now Area = 1/2*30*12 = 180 cm
Area =180 cm
If you like plz mark as brainliest ans.
