C'mon Zidan...you tired or something?
That's easy...show us some effort...

hi DenisB

like this :

area 1
(12*12)/2=72*2
=144cm2

area 2
(12*12)=144cm2

total area (144cm2*144cm2)
=288cm2

It's correct..!

How do you define Area 1? It seems you are trying to combine the two end-triangle into one measurement, but you are off by a factor of 2. (12x12)/2 = 72, not 144.

There are two congruent isosceles trapezoids, so the total area is: see here.
$\large{2\cdot\left(6\cdot\dfrac{24+12}{2}\right)= 216}.$
