Find the perimeter of the given figure.
A)48 cm
B) 49 cm
C)54 cm
D) 50 cm
E)None of these
Correct Answer:
D
Solution :
Option (d) is correct. Here, the given rectilinear figure is as follow: Now, BM = AH = 8 cm, MN = GF = 3 cm, NC = ED = 8 cm and AB = DC = 5 cm So, the required perimeter = AH + GH + GF + EF + ED + DC + BC + AB \[=8cm+1cm+3cm+1cm+8cm+5cm\]\[+\left( 8+3+8 \right)cm+5cm=\left( 31+19 \right)cm=50cm\] Rest of the options is incorrect because of the correctness of option (d).
