Solution:

(a) Perimeter of square = 4 x side

= 4 x 25 = 100 cm

(b) Perimeter of rectangle = 2 x (length + breadth)

= 2 x (40 + 10)

= 2 x 50 = 100 cm

(c) Perimeter of rectangle = 2 x (length + breadth)

= 2 x (30 + 20)

= 2 x 50 = 100 cm

(d)Perimeter of triangle = Sum of all sides

= 30 cm + 30 cm + 40 cm = 100 cm

Thus, all the figures have same perimeter
