Solution

## Steps: 2 Marks Application: 1 Mark Result: 1 Mark Given that Area of the shaded portion = 104 m2 The circle is divided into 8 equal parts Area of the circle = (8)×104                            = 20 m2 Area of unshaded part = Total area - shaded area                                       = 20 - 104 m2                                       = 80−104m2                                       = 704 = 17.5 m2 Hence, area of the unshaded portion is 17.5 m2
