This worksheet uses the concrete representation of the area of congruent rectangles with lengths given in different metric measures to aid students in mastering unit conversion for area.

In section A, pupils will label congruent rectangles in mm, cm and m and find the area of the rectangles in mm², cm² and m². This concept flows into section B, here students will use the area of rectangles to show that conversions are true.

Section C looks at the multiplications and divisions that are required when converting between mm², cm² and m².

Pupils will use these in section D where they will complete 12 conversions.

Converting to and from km² is introduced in section E and lastly pupils will find the sums of two areas in section F.
