Every unit of length has a corresponding unit of area, namely the area of a square with the given side length. Thus areas can be measured in square metres (m 2), square centimetres (cm 2), square millimetres (mm 2), square kilometres (km 2), square feet (ft 2), square yards (yd 2), square miles (mi 2), and so forth. Algebraically, these units can be thought of as the squares of the Area of a triangle (1) Area of a triangle (2) Area of a triangle (3) Area of parallelogram Volume –counting cubes Volume of a cuboid Recognise that shapes with the same areas can have different perimeters and vice versa. Recognise when it is possible to use formulae for area and volume of shapes. Calculate the area of parallelograms and Area of a triangle. Area of a two-dimensional shape is the space occupied by the shape. This area can be found by dividing the shape into unit squares and determining the number of unit squares in the shape as each unit square occupies one square unit space.
