Go 15 units of distance in any direction. Turn 90 degrees clockwise and go 15 units of distance in a straight line. Turn 90 degrees clockwise and go 15 units of distance in a straight line. Turn 90 degrees clockwise and go 15 units of distance in a straight line.
You will have travelled along a square route whose total distance is 60 units. Alternatively you could have turned counter clockwise each time.

Well, honey, if a square has an area of 60 square inches, then the side length would be the square root of 60, which is approximately 7.75 inches. So, grab your ruler and measure away!
The square root of 60 is the square root of 2 x 2 x 3 x 5. When that is simplified, a 2 comes out from under the radical sign, resulting in a final answer of 2 radical 15.
r=square root sign. r(6)*r(10)=r(6*10)=r(60)=2r(15)
The square root of 225 is 15. Since the side length of a square is just the square root of the area, the side length must be 15. As a side note, the perimeter is four times the square root of the area, or in this case, 60.
in a calculator work out 80² - 60² then square root the answer.
