MCQ
If $PQ = 28\ cm,$ then the perimeter of $\triangle\text{PLM}$ is :
  • A
    $48\ cm$
  • ✓
    $56\ cm$
  • C
    $42\ cm$
  • D
    $28\ cm$
✓

Answer

Correct option: B.
$56\ cm$
We know that $ ,PQ =\frac{1}{2}(\text{perimeter of }\triangle \text{ PLM})$
$\Rightarrow 28$
$=\frac{1}{2}$
$(\text{Perimeter of }\triangle\text{PLM)}$
$\Rightarrow (\text{Perimeter of}\triangle\text{PLM)} = 28 \times 2 = 56 \text{ cm}$
