Firstly, we would find the fractional part of the circle and then express it as a percentage.
The circle has 4 sub-divisions and a part of it is shaded. Thus, the fractional part of the shaded area is:
[tex]\frac{1}{4}[/tex]
Expressing this as percentage, we have:
[tex]\frac{1}{4}\times100=25\text{\%}[/tex]
Hence, the percentage represented by the shaded area is 25%
