Question

W

Answer 1

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 $ABCD \sim QRST$

It means that the side lengths of QRST will also be the same

Side $QT = 4$

This means that:

$m =QT$

So, we have:

$m = 4$
