Homework Statement

The Attempt at a Solution
Area of square = 25cm^2 therefore
Area of the shaded area = 25 - (Area of A + Area of B + Area of C)
Area of A = Area of C
Therefore, Area of the shaded area = 25 - (2 * Area of A + Area of B)
Area of A = [(5 * 5 * 3.14) / 4] - Area of B
Area of A = 19.625 - Area of B
Plug back into the original equation
Area of the shaded area = 25 - (39.25 - Area of B)
How on Earth would you find the area of B? I was thinking about applying some formulas regarding finding an area of a sector ([tex]r^2 * theta * 0.5[/tex]), then subtracting it by the triangular area, but it involves trigonometry and this problem does not require the knowledge of trigonometry. Any ideas?
