A rectangle of certain dimension 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 :
A.
24 cm
AnswerB.
28 cm
C.
36 cm
D.
48 cm
Answer: Option A
Solution
Answer: Option A
Solution:
Required perimeter := (AB + BC + CP + PQ + QR + RA)
= AB + BC + (CP + QR) + (PQ + RA)
= AB + BC + AB + BC
= [2 (8 + 4)] cm
= 24 cm
