I can calculate the area of rectangles, triangles, parallelograms and trapeziums efficiently.
I can calculate the area of rectangles, triangles, parallelograms and trapeziums efficiently.
Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Trapezium - A trapezium is a quadrilateral with exactly one pair of parallel opposite sides. The plural of trapezium can be referred to as trapezia or trapeziums.
Pupils might find the area of parallelograms and triangles by multiplying the length of two adjacent edges which are not perpendicular.
Calculating the area of a shape involves multiplying two perpendicular lengths. These may not be horizontal and vertical in the shape's initial orientation.

parallelogram - $$A = bh$$
trapezium - $$A = \frac{1}{2} \times (a + b)h$$
triangle - $$A = \frac{1}{2} bh$$
