Question

Match the shapes (each sides measures 2 cm) in column I with the corresponding perimeters in column II:

Column I	Column II
(A)	(i) 16 cm
(B)	(ii) 20 cm
(C)	(iii) 24 cm
(D)	(iv) 28 cm
	(v) 32 cm

Answer 1

Column I	Column II
(A)	(iv) 28 cm
(B)	(i) 16 cm
(C)	(ii) 20 cm
(D)	(iii) 24 cm

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
