Answer: 400 - 100π cm² or 100 (4 - π) cm²
Step-by-step explanation:
The length of the square = 20cm
Area of square= a²
Therefore the area of the given square is 20*20 = 400 cm²
The circle is inscribed in the square, so the radius of circle= half of the side of the square
r = a/2 = 20/2 = 10cm
The area of circle = πr²
Therefore the area of the given circle is π*(10)² = 100π cm²
The area of the shaded region= Area of square - Area of the Circle
The area of the shaded region= 400 - 100π cm² = 100(4 - π) cm²
