Q. The perimeter of a square piece of tissue paper is 3636 centimeters. How long is each side of the tissue paper?\newline​_____ centimeters
  1. Understand the problem: Understand the problem.\newlineWe need to find the length of one side of a square when we know the perimeter of the square.\newlineA square has four equal sides, so the perimeter of a square is four times the length of one side.
  2. Set up the equation: Set up the equation.\newlineLet the length of one side of the square be xx centimeters.\newlineThe perimeter PP of a square is given by P=4×xP = 4 \times x.\newlineWe know the perimeter is 3636 centimeters, so we can write the equation as 36=4×x36 = 4 \times x.
  3. Solve for x: Solve for x.\newlineTo find xx, we need to divide both sides of the equation by 44.\newline36÷4=x36 \div 4 = x\newlinex=9x = 9
  4. Check the result: Check the result.\newlineIf each side of the square is 99 centimeters, then the total perimeter would be 9 cm×4=36 cm9 \, \text{cm} \times 4 = 36 \, \text{cm}, which matches the given perimeter.
