Content includes:

• finding the area of a composite figure made up of rectangles and squares,

• finding one dimension of a rectangle given the other dimension and its area/ perimeter,

• finding the length of one side of a square given its area/ perimeter,

• solving word problems involving the area/ perimeter of squares and rectangles.

Note:

• Area of Rectangle = Length x Breadth

• The opposite sides of a rectangle are equal

• The length and breadth of a square are equal, i.e. Length of Square = Breadth of Square

Stop at 4.45 min as you will only learn area of a triangle in Primary 5.
