The ratio of the area of the shaded portion to that of the whole figure is ______.

Dear Student

The ratio of the area of the shaded portion to that of the whole figure is 1: 6.
Area of the shaded figure = 2 × 1

= 2 sq. units Area of whole figure = 3 × 4 = 12 sq. units

The ratio of the area of the shaded portion to that of the whole figure is = 2: 12 = 2/12

= 1/6 = 1: 6


Thanks
