Help pls!! Which scale factor was used to transform triangle MNP to triangle RST?

Answer:
[tex]\boxed{\textsf{ The sacle factor is \textbf{3.5} . }}[/tex]
Step by step explanation:
Here two triangles are given to us . The two triangles are ∆MNP and ∆RST. They are similar to each other . That is ,
[tex]\sf\implies \triangle MNP \sim \triangle RST [/tex]
Now we know that the corresponding sides of the similar triangles are proportional . Hence here ,
[tex]\sf\implies \dfrac{MN}{RS}=\dfrac{NP}{ST}=\dfrac{MP}{RT} [/tex]
Here we are given the value of side NP as 7 and ST as 2 . So here we can find out the scale factor by dividing these two .
[tex]\sf\implies Scale \ Factor = \dfrac{ NP}{ST}\\\\\sf\implies Scale \ Factor = \dfrac{7}{2} \\\\\sf\implies \boxed{\pink{\frak { Scale \ Factor = 3.5 }}}[/tex]
