Area of Trapeziums, Rhombuses & Kites

Three new shapes, but no new magic — each one is just a clever rearrangement of rectangles and triangles you already know. Two tidy formulas cover the lot.

1Where it comes fromTwo copies of a trapezium make a parallelogram. Watch it happen. 2How to do it½(a+b)h for trapeziums, ½d₁d₂ for kites and rhombuses, with practice. 3Where it gets trickyWhich measurement to use — and which one is a decoy. 4Out in the wildA festival kite, a block of land, and working backwards.
