This is quite depressing. You are old enough to be at your PC asking away, but you don't know the (very) basics of geometry....
Anywat, the answer is d. 16cm
that's the reasoning :
Perimeter = sum of all the sides.
In a square, all sides are equal, i.e.
Perimeter = measure of the side * 4

The answer is D.
The FOUR sides of a square are all equal.
The perimeter is the sum of all the sides.
So, either 4 + 4 + 4 + 4 = 16 or 4 sides x 4 cm = 16 cm

A square has four sides, all equal in length. So, to find four sides, you take 4+4+4+4= 16 (or 4 x 4 = 16 in short).
