| (i) \[\Delta ABC\] |
| (ii) rectangle BCDE |
A)
(i) (ii) \[8\frac{1}{60}cm\] \[5\,cm\]
B)
(i) (ii) \[5\,cm\] \[10\frac{1}{6}cm\]
C)
(i) (ii) \[8\frac{1}{60}\,cm\] \[10\frac{1}{5}\,cm\]
D)
(i) (ii) \[8\,cm\] \[23\,cm\]
Correct Answer: C
Solution :
(i) Perimeter of \[\Delta \,ABC=\left( 4\frac{2}{3}+\frac{3}{4}+2\frac{3}{5} \right)\,cm\] \[=\left( \frac{14}{3}+\frac{3}{4}+\frac{13}{5} \right)\,cm=\frac{481}{60}=8\frac{1}{60}\,cm\] (ii) Perimeter of rectangle BCDE \[=2\left( \frac{5}{2}+2\frac{3}{5} \right)\,cm\] \[=2\left( \frac{5}{2}+\frac{13}{5} \right)cm=2\left( \frac{25+26}{10} \right)\,cm\] \[=2\left( \frac{51}{10} \right)cm=\frac{51}{5}cm=10\frac{1}{5}cm\]
