(a) The perimeter of the square
      = Sum of all the four side = 4 \times  side
      = 4 \times  25
      = 100 cm

(b)The perimeter of the rectangle
= SUm of all the sides = 2 \times [length + breadth )
= 2 \times (20 + 30)
= 2 \times 50
= 100

(c)The perimeter of the rectangle
= Sum of all the sides = 2 \times [length + breadth ]
= 2 \times (40 + 10)
= 2 \times 50
= 100 cm

(d)The perimeter of the triangle
= Sum of all three sides of the triangle
= 30cm + 30cm + 40cm
=100cm

We conclude all the given figures have the same perimeter.
