ANSWER :
Q1. length = 25 cm, breadth = 16 cm
ANS. Perimeter = 2 x (Length + Breadth)
Perimeter = 2 x (25 + 16)
Perimeter = 2 x 41
Perimeter = 82 cm
Q2. length = 35 cm, breadth = 28 cm
ANS. Perimeter = 2 x (35 + 28)
Perimeter = 2 x 63
Perimeter = 126 cm
Q3. length = 25.5 cm, breadth = 20.5 cm
ANS. Perimeter = 2 x (25.5 + 20.5)
Perimeter = 2 x 46
Perimeter = 92 cm
