because the paralelogram has two sets of parallel sides, the formula for it is very similar to a rectangle! so
area=50cm*20cm=1000cm2=0.1m2

A = base x height
A = 50 x 20
A = 1000 cm^2

Imagine you clip off the triangle on one end of the parallelogram and fit it to the triangle on the other end so that the result is a rectangle.
b will still be 50 cm and h will still be 20 cm
The area of the rectangle is b x h
_____
/|_____/ <--add the clipped triangle here
^
clip here
...............<--b-->
............... _____ [ignore the spacing dots]
Result is |____//| or without trying to show the triangles fitting,
_______
|______| still h tall
still b long
A = bh
