To do:  We have to find the perimeter of each of the given figures.

Solution:

We know that,

Perimeter is defined as the length of the outline of a shape.

To find the perimeter of a figure, just add the lengths of all the sides of the figure.

Therefore,

(a) In the given figure,

Sum of the sides $=25+25+25+25$

$=100\ cm$

(b) In the given figure,

Sum of the sides $= 10+40+10+40$

$=100\ cm$

(c) In the given figure,

Sum of the sides $= 30+20+30+20$

$=100\ cm$

(d) In the given figure,

Sum of the sides $= 30+40+30$

$= 100\ cm$

All the given figures have same perimeter.
