What is the area of the irregular polygon shown below?

Letter A, the answer is 121.5 square ft.

Step-by-step explanation:

Area of given figure is combination of area of rectangle and area of Pentagon

Area of rectangle = length x width

                              = 6 x10

                              = 60  sq units

Area of pentagon = where a = apothem and p = perimeter

      Area of pentagon =

                                    =61.5  sq units

Area of the given figure = area of rectangle + area of pentagon

                                  =  60 + 61.5

                                     121.5 sq units
