Find the area of the given figure

The correct answer is: 24 square units

The given figure is made up of horizontal and vertical rectangles.

Each figure have consist of square units.

We just need to measure the square inside the figure.

Squares inside verticle rectangle = 6 cross times 2 = 12 square units

 Squares inside the horizontal rectangle = 3 cross times 4 = 12 square units

 The total area of figure = Squares inside verticle rectangle + Squares inside the horizontal rectangle

                                       = 12 + 12 

                                      = 24 square units

 So the correct option is a.
