Answer 2

Answer:

a) Perimeter = 56 cm

b) Perimeter = 309.6 cm

c) Perimeter = 748 cm

d) Length = 20 cm

Step-by-Step Explanation:

a) l = 18 cm

   b = 10 cm

   Perimeter = 2(l + b)

                    = 2[(18) + (10)]

                    = 2(28)

                    = 56 cm

b) l = 98.2 cm

   b = 56.6 cm

   Perimeter = 2(l + b)

                    = 2[(98.2) + (56.6)]

                    = 2(154.8)

                    = 309.6 cm

c) l = 218 cm

   b = 156 cm

   Perimeter = 2(l + b)

                    = 2[(218) + (156)]

                    = 2(374)

                    = 748 cm

d) l = ?

   b = 14 cm

   Perimeter = 2(l + b) = 68

                    => 2[l + (14)] = 68

                    => 2l + 28 = 68

                    => 2l = 68 - 28

                    => 2l = 40

                    => l = 40/2

                    => l = 20 cm
