Answer»

(1) The Perimeter of Rectangle = (21 + 2b)
= (2 × 2 + 2 × 3)
= 4 + 6
= 10 cm

(2) The Perimeter of Rectangle = (21 + 2b)

= (2 × 2 + 2 × 4)

= 4 + 8

= 12 cm

(3) The Perimeter of Rectangle = (21 + 2b)

= (2 × 3 + 2 × 4)

= 6 + 8

= 14 cm

(4) The Perimeter of Rectangle = (21 + 2b)

= (2 × 5 + 2 × 4)

= 10 + 8

= 18 cm

(5) The Perimeter of Rectangle = (21 + 2b)

= (2× 5 + 2 × 2)

= 10 + 4

= 14 cm

(6) The Perimeter of Rectangle = (21 + 2b)

= (2 × 3 + 2 × 6)

= 6 + 12

= 18 cm

(7) The Perimeter of Rectangle = (21 + 2b)

= (2 × 4 + 2 × 6)

= 8 + 12

= 20 cm

(8) The Perimeter of Rectangle = (21 + 2b)

= (2 × 5 + 2 × 6)

= (10 + 12)

= 22 cm

(9) The Perimeter of Rectangle = (21 + 2b)

= (2 × 8 + 2 × 6)

= 16 + 12

= 28 cm

(10) The Perimeter of Rectangle = (21 + 2b)

= (2 × 7 + 2 × 9)

= 14 + 18

= 32 cm
