Q. A square sticky note has an area of 49 square centimeters49\,\text{square centimeters}. How long is each side?\newline​____\_\_\_\_ centimeters
  1. Understand the problem: Understand the problem.\newlineWe are given the area of a square sticky note and need to find the length of one of its sides.\newlineA square has all sides of equal length, so the area is calculated by squaring the length of one side.\newlineArea of a square =side length×side length.= \text{side length} \times \text{side length}.
  2. Set up the equation: Set up the equation to solve for the side length.\newlineLet the side length be represented by 'ss'.\newlineSo, the equation based on the area of a square is:\newlines×s=49 cm2s \times s = 49 \text{ cm}^2
  3. Solve for 's: Solve for 's'.\newlineTo find 's', we need to take the square root of both sides of the equation:\newlines×s=49 cm2\sqrt{s \times s} = \sqrt{49 \, \text{cm}^2}\newlines=7 cms = 7 \, \text{cm}
