A rectangle of certain dimensions is chopped off from one corner of a larger rectangle as shown. AB = 8 cm and BC = 4 cm. The perimeter of the figure ABCPQRA (in cm) is :

1. 24
2. 28
3. 36
4. 48

Required perimeter = (AB + BC + CP + PQ + QR + RA)

= AB + BC + ()CP + QR + (PQ + RA)

= AB + BC + AB + BC = 2 (AB + BC)

= [2 (8 + 4)] cm = 24 cm
