MCQ
In the given figure, the perimeter of $\triangle \text{ABC}$ is:
- A$15 \ cm$
- ✓$30 \ cm$
- C$60 \ cm$
- D$45 \ cm$
✓
Answer
Correct option: B.
$30 \ cm$
$\ce{AQ = AR =}4$
Similarly,
$\ce{PC=CQ}=5$
Similarly,
$\ce{BP=BR}=6$
Perimeter $= \ce{AB + BC + CA}$
Perimeter $= \ce{AR + RB + BP + PC + CQ + QA}$
$=4+6+6+5+5+4$
$=30 \ cm$
Similarly,
$\ce{PC=CQ}=5$
Similarly,
$\ce{BP=BR}=6$
Perimeter $= \ce{AB + BC + CA}$
Perimeter $= \ce{AR + RB + BP + PC + CQ + QA}$
$=4+6+6+5+5+4$
$=30 \ cm$
