Answer:
Step-by-step explanation:
When the quadrants of the circle on the vertex of the square are joined a circle of radius 1 cm is formed.
To get the area of the shaded region we need to get the area of the unshaded regions .
The area of the circle at the center of the square = 3.14 × (2/2)² = 3.14 cm²
Area of the four quadrants = 3.14 × 1² = 3.14 cm²
Area of the square = 4 × 4 = 16 cm²
The area of the shaded region = area of the square - ( area of the circle at the center + The total area of the quadrants)
= 16 - (3.14 + 3.14) = 16 - 6.28
= 9.72 cm²
