THE ANSWER IS DEFINITELY C
the area of a parallelogram is= b*h
so let the height = x
let base = 2x
so area= 2x^2=128
therefore x^2 = 64
x=8
perimeter>2b+2h
therefore it is greater than 48
if perimeter is 48, shape is a rectangle
so not B
for perimeter to be 128 cm,
the side has to be 48 cm long
which would screw up the base/height badly
and thus screw up the area as well
this is by using common sense, try
and imagine the parallelogram with these
dimension. you will see what i mean
so not A
