Explanation:
(A) Perimeter of figure = Sum of all sides
= AB + BC + CD + DE + EF + FG + GH + HI + IJ + JK + KL + LM + MN + NA
= 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
= 28 cm
(B) Perimeter of figure = Sum of all sides
= AB + BC + CD + DE + EF + FG + GH + HA
= 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
= 16 cm
(C) Perimeter of figure = Sum of all sides
= AB + BC + CD + DE + EF + FG + GH + HI + U + JA
= 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
= 20 cm
(D) Perimeter of figure = Sum of all sides
= AB + BC + CD + DE + EF + FG + GH + HI + IJ + JK + KL + LA
= 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
= 24 cm
