Area of Trapezium
Product Code : SCL-MK-12463
Area of Trapezium (SKU SCL-MK-12463) is a multicolour acrylic model with two congruent trapezium pieces that can be arranged to form a parallelogram. This trapezium area model helps students understand why the area equals half the sum of the parallel sides multiplied by the perpendicular height, with sides a and b and height h clearly marked.
Specifications
The model is made from 3 mm (0.3 cm) multicolour acrylic on a 20 x 15 cm base frame, with two congruent detachable trapezium pieces, marked parallel sides a and b, a perpendicular height h with a right-angle indicator, and a separate plastic storage box.

Applications of the trapezium area model
Students place the two congruent trapezia side by side, one rotated, to form a parallelogram whose base is a + b and whose height is h, so they can see that one trapezium is half of that parallelogram and derive the area formula themselves.
- Deriving area of a trapezium = 1/2 (a + b) h
- Forming a parallelogram from two congruent trapezia
- Identifying parallel sides and perpendicular height
- Middle-school mensuration and geometry demonstrations

Frequently asked questions
How does the model derive the trapezium formula?
Two congruent trapezium pieces are arranged to form a parallelogram with base a + b and height h, so each trapezium has half that area: 1/2 (a + b) h.
