    The perimeter of a circular plate is 132 cm. Find its area. (Use π = 227 22 7) Solution: Let the radius of the plate be r. Then, Perimeter = 2πr. 132 cm = 2 × 227 22 7 × r. 132 cm = 447 44 7 × r. 447 44 7 × r = 132 cm. r = 132 × 744 7 44. r = 92444 924 44. r = 21 cm. Therefore, area of the plate = πr 2 = 227 22 7 × 21 2 cm 2.
