The perimeter of a square is equal to the perimeter of a rectangle of length 17 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 correct choice from the following:  A) 23.57  B) 23.54  C) 23.5  D) 24.35  E) 24.51

Rationale: "let the side of the square be a cm . perimeter of the rectangle = 2 ( 17 + 14 ) = 62 cm perimeter of the square = 62 cm i . e . 4 a = 62 a = 15.5 diameter of the semicircle = 15.5 cm circumference of the semicircle = 1 / 2 ( ∏ ) ( 15.5 ) = 1 / 2 ( 22 / 7 ) ( 15.5 ) = 24.35 cm to two decimal places answer : d"
Answer: D
