Correct Answer: 15 cm
Solution :
$\triangle$ABC ~ $\triangle$PQR
Perimeter($\triangle$ABC) = 36 cm
Perimeter($\triangle$PQR) = 24 cm
PQ = 10 cm
$\frac{AB}{PQ}$ = $\frac{\text{Perimeter($\triangle$ABC)}}{\text{Perimeter($\triangle$PQR)}}$
⇒ $\frac{AB}{10}$ = $\frac{36}{24}$
⇒ AB = $\frac{360}{24}$ = 15 cm
Hence, the correct answer is 15 cm.
