Correct!
To answer this, we need to know the expression for the area of a square which is the square of its side length or:
Area = a²
Solving for the side length,
a = √area
a = √144x²
a = 12x
Therefore, the side length is 12x.
Area = a²
Solving for the side length,
a = √area
a = √144x²
a = 12x
Therefore, the side length is 12x.
You just said that the + with a line under it was correct now your saying that 12x is correct which one is the right one.
If your doing this in conexus with Mrs. Martin it’s no solution. Idk why, but it is.
Nvm it’s B, sorry.
