Answer 1

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

$\begin{gathered} PQ^{\prime}=2.5\times PQ=(8\times2.5)cm=20\operatorname{cm} \\ QR^{\prime}=(17\times2.5)cm=42.5\operatorname{cm} \\ RP^{\prime}=(15\times2.5)cm=37.5\operatorname{cm} \end{gathered}$

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