If the dimensions of a parallelogram are increased by a factor of two, how will the perimeter of the object be affected? increase by a factor of four decrease by a factor of one-fourth increase by a factor of two decrease by a factor of one-half

Let
x> length major side  parallelogram
y> length minor side  parallelogram
we know that 
[perimeter]=(2x+2y)
Po=(2x+2y)

If the dimensions of a parallelogram are increased by a factor of two
then
x1=2x
y1=2y
P1=2x1+2y1> 2*[2x]+2*[2y]> P1=2*[2x+2y]
P1=2*Po

the answer is 
the new perimeter increase by a factor of two

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
