A scaled copy of a shape will be similar to the shape.
The side length m is 4
From the attached image,
All sides of ABCD are the same (i.e. 10)
Since [tex]ABCD \sim QRST[/tex]
It means that the side lengths of QRST will also be the same
Side [tex]QT = 4[/tex]
This means that:
[tex]m =QT[/tex]
So, we have:
[tex]m = 4[/tex]
