From the above figure, we find that:
Perimeter of shaded portion = 10 units
Perimeter of whole design = 18 units
Area of shaded portion = 6 sq. units
Area of whole design = 20 sq. units
Also, area of unshaded portion = Total area - Area of the shaded portion
= 20 - 6 = 14 sq. units
a) Ratio of perimeter of the shaded portion to the perimeter of the whole design
=
Perimeter of shaded portion
Perimeter of whole design
=

=

[on dividing numerator and denominator by 2]
b) Ratio of area shaded portion to the area of unshaded portion
=
Area of shaded portion
