ANSWER
Each side of the chip is 5 centimeters long.
EXPLANATION
The chip is in the form of a square.
The formula for finding the area of a square is
[tex]Area=l^2[/tex]
We were given in the question that, the area is 25 square centimeters. This means that,
[tex]25=l^2[/tex]
We take the square root of both sides to get,
[tex]\sqrt{25}=l[/tex]
[tex]\Rightarrow 5=l[/tex]
Hence the length of the square technology chip is 5 centimeters
