I will like to stop at this point. I don't think I can continue. Please return my earning back as I'm not in this because of the prize. I will still be observing but from background.

I wish you guys the very best.

Signing out.. Peace!!

ΔPTRS=2*ΔSUT

=48cm²

reason is that parallelogram on the same base and between thesmane parallel lines are equal.

Bring solution please

It does n oh t take much to write the solution

Mrshape:
Bring solution please

ptrs is a parallelogram
area of parallelogram=bxh
sur is a triangle
area of triangle=1/2bh
24=1/2*8*h
h=24/4=6
area of ptrs=8*6=48cm²

We move

Spartancosta:
ptrs is a parallelogram area of parallelogram=bxh sur is a triangle area of triangle=1/2bh 24=1/2*8*h h=24/4=6 area of ptrs=8*6=48cm²

I'm I right?

Spartancosta:
ptrs is a parallelogram
area of parallelogram=bxh
sur is a triangle
area of triangle=1/2bh
24=1/2*8*h
h=24/4=6
area of ptrs=8*6=48cm²

Hmm long way

Simply
Parallelogram on same base and parallel =2xTriangle of same base and parallel

Spartancosta:
ptrs is a parallelogram
area of parallelogram=bxh
sur is a triangle
area of triangle=1/2bh
24=1/2*8*h
h=24/4=6
area of ptrs=8*6=48cm²

All these ain't necessary its a simple theorem under parallelogram
