A square technology chip has an area of 25 square centimeters how long is each side of the chip
grigory [225]

ANSWER

Each side of the chip is 5 centimeters long.


<u>EXPLANATION</u>

The chip is in the form of a square.


The formula for finding the area of a square is

Area=l^2


We were given in the question that, the area is 25 square centimeters. This means that,


25=l^2


We take the square root of both sides to get,


\sqrt{25}=l


\Rightarrow 5=l


Hence the length of the square technology chip is 5 centimeters
