How can you use the map to argue that alexander was great?

Certainly! Considering the land that was ruled by Philip II of Macedon extended far less, his son (Alexander) managed to conquer the middle east, Southeast Europe and a profound part of West Asia by 23! In addition, during his time, no other empire had stretched so far at all. He is a short-lived great of the history of Conquers...

 300 ft.²   .

Explanation:

We need to find the area of the rectangle:

Area:  A = L * w = length * width = 12 ft. * 18 ft. = 216 ft.²

Then we need to find the area of the TRAPEZOID that is on top of the rectangle:

Area:  A = (1/2) * (base 1 + base 2) * height 
 
             = (1/2) * (18 ft. + 10 ft.) * 6 ft.
   
             = (1/2) * ( 28 ft.) * (6ft.)
      
             =   84 ft.²

Now, we add the 2 (TWO) areas together, to get the

   216 ft.²  +  84 ft.²  = 300 ft.²  .
