## anonymous one year ago The formula for finding the area of a square that has a side length, s, is A = s2. If a square has an area of 40 square units, what is the length of a side?

1. mathstudent55

$$A = s^2$$ $$40 = s^2$$ $$s^2 = 40$$ Since you want s, take the square root of both sides: $$s = \sqrt {40}$$ Now simplify the root.

4 * 10 or is it 2 * 20

3. anonymous

$10\sqrt{2}$
