Answer: 2b +2f =5----------(1)
3b +4f =8.5---------(2)
From eqn 1
2f = 5 -2b
f = (2.5 - b)
Put f =(2.5-b) in eqn 1
3b + 4(2.5-b) =8.5
3b +9 - 4b =8.5
-b = -0.5
b = $0.5

Answer:
Deena is correct.
Step-by-step explanation:
Assume that the radius of the circle is 1.
The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).
Finally, the ratio of the square to the circle, in area, will be
(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi
We can conclude that the white area is about 35%.
