Q 1. Find the perimeter of each of the following figures :
The perimeter of the following figures-
Perimeter = sum of all sides
Therefore,
(a) Perimeter = 4 cm + 2cm +1 cm +5cm = 12 cm
(b) Perimeter = 23 cm + 35 cm + 40cm + 35cm = 133 cm
(c) Required perimeter = 15cm + 15 cm + 15 cm +15 cm = 60 cm
(d) Required perimeter= (4 + 4 + 4 + 4 + 4) cm = 20 cm
(e) Perimeter = 4cm + 0.5 cm +2.5cm +2.5cm + 0.5cm +4cm +1cm = 15cm
(f) Perimeter = Sum of all sides = 4(4cm) + 4(1 cm) + 8(3 cm) + 4(2cm) = (16 + 4 + 24 + 8)cm =52 cm
