    Irregular shapes are those shapes that do not have equal sides or equal angles. In order to find the area of an irregular shape, it can be decomposed or divided into multiple familiar shapes and then the area of those can be added to get the total area.

    The above given figure is an example of irregular shapes.
    Thus, we divide the above shape into a rectangle of sides 2in.cross times 9in and square of side 3in, each
    Area of rectangle = 9 × 2 = 18 square inches
    Area of a square = 3 × 3 = 9 square inches
    Total area = Area of rectangle + Area of a square
    Total area = 18 + 9 = 27 square inches
