then the measure of the side of square is , or the square is by
The equation that can be set up is:
the area of a square is
the area of a rectangle is
since the resulting rectangle has an area less, we have:
.........solve for
...............the cancels out leaving us:
.... divide both sides by
so, the length of the rectangle is and
the width of the rectangle is
Therefore we can solve this rectangle size as by .
The area comes out to be
