Answer:

4%

Step-by-step explanation:

[tex]Percentage\:Error=\frac{Error}{Correct\:Value}*100\%[/tex]

The exact or correct value  is 5cm

The inaccurate value is 5.2cm

The error value is |5.2-5.0|=0.2

This implies that:

[tex]Percentage\:Error=\frac{0.2}{5}*100\%[/tex]

This simplifies to:

[tex]Percentage\:Error=0.04*100\%[/tex]

[tex]Percentage\:Error=4\%[/tex]

Hence the percentage error is 4%
