Rectangle ABCD has AB = 4 and BC = 8. Construct arc AE centered at B with E on side BC and construct arc CF centered at E with F along side AD. What is the area of AFCE, the region shaded in blue?
A rectangle has a side length equal to 10. Two semicircles are constructed with their diameters equal to the length of 10 and along opposite sides of the rectangle, as shown. A circle is inscribed between the intersection points of the semicircles and tangent to the two sides of 10 on the rectangle. What is the area of the shaded region in which the two semicircles are overlapping?
The 2 diagonals of this rectangle divide it into 4 triangles.
If the area of the shaded region is 42, then what is the area of the rectangle?
