Solution

Finding that the two triangles $A B C a n d P Q R$ are congruent or not :
In $∆ A B C a n d ∆ R P Q$ ,
$A B = R P = 3.5 c m$
$B C = P Q = 2 c m$
$A C = R Q = 5.5 c m$
Thus, $A \leftrightarrow R, B \leftrightarrow P, C \leftrightarrow Q$
Therefore, by SSS congruency criteria $∆ A B C ≅ ∆ R P Q$
