solving the area of the circle
A = π × 2^2
A = 12.57
halve
/2 = 6.29
area of the square = 4*4
16
subtract area of half circle from area of square
16 - 6.29 = 9.71

You first want to find the area of the semi circle by using the formula
A=πd ÷ 2 + d
Once you plugged everything in, it should equal 10.28
you then want to find the area of the square by using the formula
A=bh
Once you plugged everything in, it should equal 16
The last step is to subtract the two numbers, which equals 5.72ft²
