ANSWER:

We have to find new side-lengths of PQR triangle.

Original sides are.

$\begin{gathered} PQ\text{ = 8cm} \\ QR=17\operatorname{cm} \\ RP=15\operatorname{cm} \end{gathered}$

After multiplying by 2.5 we get

$\begin{gathered} PQ^(\prime)=2.5* PQ=(8*2.5)cm=20\operatorname{cm} \\ QR^(\prime)=(17*2.5)cm=42.5\operatorname{cm} \\ RP^(\prime)=(15*2.5)cm=37.5\operatorname{cm} \end{gathered}$

These are the new sides of the P'Q'R' triangle.
