If the perimeter of a square is 40 cm, what is the length of one side? (2018)
Step 1: Understand that a square has 4 equal sides.
Step 2: Know that the perimeter of a square is calculated by adding the lengths of all 4 sides together.
Step 3: Use the formula for the perimeter of a square: Perimeter = 4 × side.
Step 4: Substitute the given perimeter (40 cm) into the formula: 40 = 4 × side.
Step 5: To find the length of one side, divide the perimeter by 4: side = 40 / 4.
Step 6: Calculate the division: side = 10 cm.
Perimeter of a Square – The perimeter of a square is calculated by adding the lengths of all four sides, which is equivalent to 4 times the length of one side.
