Find the perimeter of each of the following figures :

Explanation

We know that, the perimeter of any figure represents the sum of its all side
Hence, the perimeter of any given figure= Sum of all the sides.
(a) Perimeter =` 1 + 2 + 4 + 5= 12` cm
Hence, the perimeter is 12 cm.
(b) Perimeter=`23+35+35+40=13`cm
Hence, the perimeter is` 13`3 cm.
(c) Perimeter = `15 + 15 + 15 + 15 = 60` cm.
Hence, the perimeter is 60 cm.
(d) Perimeter = `4 + 4 + 4 + 4 + 4 = 20 `cm.
Hence, the perimeter is 20 cm.
(e) Perimeter =` 1 + 4 + 0.5 + 2.5 + 2.5 + 0.5 + 4 = 15 `cm
Hence, the perimeter is 15 cm.
(f) Perimeter =` 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 = 52 `cm.
Hence, the perimeter is` 52` cm.
