(a) \(\text{Perimeter} = \text{Sum of all the sides }= 4 \;cm + 2 \;cm + 1 \;cm + 5 \;cm \)
\(=12 \;cm\)
(b) \(\text{Perimeter} = \text{Sum of all the sides} = 23 \;cm + 35\; cm + 40 \;cm + 35 \;cm \)
\(= 133\; cm\)
(c) \(\text{Perimeter} = \text{Sum of all the sides }= 15 \;cm + 15\; cm + 15 \;cm + 15 \;cm \)
\(= 60 \;cm\)
(d)\(\text{ Perimeter} = \text{Sum of all the sides }= 4 \;cm + 4 \;cm + 4 \;cm + 4 \;cm + 4 \;cm \)
\(= 20 \;cm\)
(e) \(\text{Perimeter} = \text{Sum of all the sides} \)
\(\\=1 \;cm + 4 \;cm + 0.5\; cm + 2.5\; cm + 2.5\; cm + 0.5\; cm + 4 \;cm = 15 \;cm\)
(f) \(\text{Perimeter} = \text{Sum of all the sides}\)
\(= 4 \;cm + 1 \;cm + 3 \;cm + 2\; cm + 3 \;cm + 4\; cm + 1 \;cm + 3\; cm + 2 \;cm + 3 \;cm + 4 \;cm + 1 \;cm + 3 \;cm + 2 \;cm + 3 \;cm + 4 \;cm + 1 \;cm + 3 \;cm + 2 \;cm + 3 \;cm \)
\(= 52 \;cm\)
