You will need the Total Loan Cost Formula which is
(I'm having trouble attaching the graphic - I think the problem is with Brainly).
If nothing else, go to this web page.
It has a calculator and the formula.

I get an answer of $6,238.70
Area of the square = (9 m)^2 = 81 m^2
The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.
Area of the circle = π (4.5 m)^2 = 20.25π m^2
Then the area of the shaded region is
81 m^2 - 20.25π m^2 ≈ 17.4 m^2
Because if you multiply 2 different irrational numbers (like the following)

You will get an irrational answer.
BUT
if you multiply the same square root (which are both irrational, you get a rational number)
