The area of a square is 38 sq. cm more than the area of a rectangle of length 19 cm and breadth 17 cm. What will be the area of incircle of the square?
The area of rectangle = l × b = 19 × 17 = 323 sq. cm The area of square = 323 + 38 = 361 sq. cm The side of square = √361 = 19 cm Radius of incircle of a square = side = 19/2 = 9.5 cm
