  1. 68 square cm    
  2. 66 square cm    
  3. 24 square cm    
  4. 44 square cm    

hintHint:

 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 correct answer is: 68 square cm


    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 4cm cross times 11cm and rectangle of side 4cm cross times6cm
    Area of rectangle A= 6 × 4 = 24 square cm
    Area of rectangle B = 11 × 4 = 44 square cm
    Total area = 24 + 44 = 68 square cm
