square is best

this work involves the area and perimeter of rectangles
(i) fixing the perimeter to be 16cm
(ii) fixing the area to be 36 carpet tiles
in this way two important functions (quadratic and reciprocal) can be considered
and number work practiced along the way...

the geogebra applet by Anthony Or is helpful, with a perimeter of 20 rather than 16
