The square has an area of 25cm^2.
Area of a square is side times side.
So if the two squares are adjacent, the length of the triangle that will be formed will be 10 cm, whereas the width will remain the same.

Perimeter of a rectangle is L + W x 2.
so, 10 + 5 = 15 x 2 = 30 cm

It is like this:
                     __________________
                     I                 I                 I
                     I  A=25 cm I A = 25 cmI
                     I________ I________ I

Which means, that the sides are: 
(in cm)
          
                      ___5________5_____
                     I                 I                 I
                   5I                 I                 I5
                     I________ I________ I
                            5                  5

Asked: Perimeter of the whole rectangle formed, so, what we do is to add them all:
                 5 + 5 + 5 + 5 + 5 + 5 = 30
