Q. The area of a square notepad is 100 square centimeters100\,\text{square centimeters}. How long is each side of the notepad?\newline​_____\_\_\_\_\_ centimeters
  1. Identify Area Equation: Let ss be the side length of the square.\newlineWhich equation represents the area of a square.\newlineThe area is the product of the lengths of two sides.\newlineA=s2A = s^2
  2. Substitute Area Value: Area of square notepad: 100100 square centimeters\newlineWhich equation represents the area of a square notepad.\newlineSubstitute 100100 for AA in A=s2A = s^2.\newline100=s2100 = s^2
  3. Solve for Side Length: 100=s2100 = s^2\newlineWhat is the length of each side of the notepad?\newlineTake the square root of both sides to solve for ss.\newline100=s2\sqrt{100} = \sqrt{s^2}\newline10=s10 = s\newlineSide length of the square notepad: 1010 centimeters
