1. Step-by-step explanation:

   (a) Perimeter = Sum of all the sides

   = 4 cm + 2 cm + 1 cm + 5 cm = 12 cm

   (b) Perimeter = Sum of all the sides

   = 23 cm + 35 cm + 40 cm + 35 cm = 133 cm

   (c) Perimeter = Sum of all the sides

   = 15 cm + 15 cm + 15 cm + 15 cm = 60 cm

   (d) Perimeter = Sum of all the sides

   = 4 cm + 4 cm + 4 cm + 4 cm + 4 cm = 20 cm

   (e) Perimeter = 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) Perimeter = 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

   We know,

   • perimeter = 2 ( l + b)
   • perimeter = 2( 120 + 80)
   • Perimeter = 2( 200)
   • perimeter = 400m

   cost = 400 × 60

   cost = 24000

   hope this helps!!
