Let the parallelogram be ABCD with AB=CD=36 cm and AD=CB=27 cm. Let DE be the altitude from D on BC and AF be the altitude from A on CD. The shortest distance between the shorter sides is 12 cm.
We know that the perpendicular distance is the shortest distance between two points. So we can say that altitude DE is the shortest distance between the two short sides AD & BC. Therefore, DE=12 cm.
Now, we know that Area of Parallelogram = ½ X Base X Height. 
So Area of Parallelogram ABCD = ½ X AD X DE = ½ X AF X DC
Area of Parallelogram ABCD = ½ X 27 X 12 = ½ X AF X 36
Area of Parallelogram ABCD = ½ X 324 = ½ X AF X 36       
=  324 =  AF X 36
=  AF   = 324/36
=  AF   =  9 cm
Therefore the shortest distance between the two loger sides is 9 cm.

Area of parallelogram is Base*height
So,we can take the area of parallelogram from two ways.
Base1 * Height1 =Base2 * Height2
27 * 12 = 36 * Height2
Height2=\frac{27*12}{36}
Height2 =9 units

Perimeter of a square=160mSide of a sq= perimeter÷4therefore side = 160/4=40mNow side of a square = 40mNow area of a sq = side square = 40×40 =1600m sqArea = 1600msqHeight of paralelogram = 20msqLength=?Now length= area/height =1600/20 =80m is length.ans
