Step-by-step 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 = 133 cm
Hence, the perimeter is 133 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.
