hey guys so im stuck again
the question is
A square has an area of 400cm2
what is the length of each side?
i know its pretty easy but im sort of clueless, thanks for any help, and i apologize if im in the wrong forum
Area is generally: . But since you know its a square its or , whichever you prefer. Then you put the numbers you know in the equation.
then remove the ^2, which is called "squared" for a reason. Square root..
I'm sure you can do the rest.
