The perimeter of a square is equal to the perimeter of a rectangle of length 19 cm and breadth 14 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square. (Round off your answer to two decimal places)	Choose the most appropriate option:
A) 22.78
B) 23.54
C) 23.5
D) 24.55
E) 25.93
Let the side of the square be a cm.   Perimeter of the rectangle = 2(19 + 14) = 66 cm   Perimeter of the square = 66 cm   i.e. 4a =66   A = 16.5   Diameter of the semicircle = 16.5 cm   Circumference of the semicircle   = 1/2(∏)(16.5)   = 1/2(22/7)(16.5) = 25.93 cm to two decimal places   Answer: 25.93
