- The problem requires finding the area of a shaded region formed by a square and two quarter-circles.
- The side length of the square is given as 10 cm.
- Each quarter-circle has a radius equal to the side of the square, so r = 10 cm.
- The area of one full circle with radius 10 cm is πr² = π(10)² = 100π cm².
- Since there are two quarter-circles, their combined area is (2/4) × 100π = 50π cm².
- The area of the square is 10 × 10 = 100 cm².
- The shaded area is the area of the square minus the combined area of the two quarter-circles.
- Therefore, shaded area = 100 - 50π cm².
