What is the total area of this composite figure? all angles are right angles.

54 in.2
75 in.2
72 in.2
90 in.2

Total Area of this figure is:

90 in²

Step-by-step explanation:

Area of this figure=Area of the bigger rectangle+Area of smaller rectangle

Area of bigger rectangle = 12×6 in²

                                          =72 in²

Area of smaller rectangle=6×3 in²

                                         = 18 in²

Hence, total area of figure=72+18

                                          = 90 in²
