Answer:
solution given:
let's see only in a right-angled triangle Δ ACD.
AC=3 units
AD=5 units
since Δ ACD is a right-angled triangle. It satisfies Pythagoras law

25=9+
=25-9=16

Now
Area of rectangle Δ ACD=
similarly,

since AB=CE=2.4 units
Δ ACE is a right-angled triangle. It satisfies Pythagoras law.

now
area of trapezoid=area ofΔACD+Area of ΔABC
=6+
