The scale factor of rectangle JKLM to rectangle QRST
is
The perimeter of rectangle QRST is 12 units, and the
perimeter of rectangle JKLM is units.
The area of rectangle QRST is units, and the
area of rectangle JKLM is 128 units
If proportional dimensional changes are made to a
figure, then the perimeter will change by the
scale factor, and the area will change
by the
scale factor.
