Maths tutors/lecturers or professors have to be patient with does who are willing to learn,
You are their teacher because you learnt it first not because you are more intelligent.
Let's try this out I will bring solution tomorrow.
Hmmm
Everywhere Green.

EA = AD = x

Diagonal = semicircle diameter = √(x²+x²) = x√2

Radius of semicircle = x√2/2

Now AF² = x² -(x√2/2)²

AF² = x² - 2x²/4 = x²/2

AF = x/√2

But AF + FG = 14√2
x/√2 + x√2/2 = 14√2
2x +2x = 4*14
x = 14
R of semi circle = x√2/2 = 7√2
r of the circle = 7√2/2

Area of the green region = Area of the semicircle - Area of the circle

π (7√2)²/2 - π (7√2/2)²

π(98/2 - 98/4) = π 98/4 = 22/7 * 98/4 = 77 units²

You are correct. I got the same thing too.
