Question

In the following figure, find the ratio of the area of the shaded portion to that of the whole figure:

Answer 1

Let the area of each small triangle be 1 sq.unit.

∴ Required ratio = `"Area of the shaded portion"/"Area of the whole figure"`

= `(16  "sq.units")/(32  "sq.units")`

= `1/2`

= 1 : 2
