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+![CD^2](/tpl/images/2606/1737/9108c.png)
Now
Area of rectangle Δ ACD=![\frac{1}{2} CD*AC=\frac{1}{2}*4*3=6\: square \:units](/tpl/images/2606/1737/2ff13.png)
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+![\frac{1}{2}AB*BC=6+\frac{1}{2}*2.4*1.11=6+1.33 =7.33\: square \:units](/tpl/images/2606/1737/2a74a.png)
