This is the red 3%2F4ths of a 24ft-radius circle plus 
1%2F4 of a 4ft-radius circle.

The area of a full circle is A = pr².

The area of the big red 3%2F4 circle = 3%2F4pr².
 
=  3%2F4p·r² = 3%2F4·(3.14)·(24)².

The area of the small green 1%2F4 circle = 1%2F4pr².
 
=  1%2F4p·r² = 1%2F4·(3.14)·(4)².


Total area = 3%2F4·(3.14)·(24)² + 1%2F4·(3.14)·(4)².

Total area = 1356.48 + 12.56 = 1369.04 square feet.
