If a rectangle has a length of 10 cm and a width of 5 cm, what is its perimeter? (2022)

Step 1: Identify the length of the rectangle, which is 10 cm.
Step 2: Identify the width of the rectangle, which is 5 cm.
Step 3: Use the formula for the perimeter of a rectangle, which is Perimeter = 2 × (length + width).
Step 4: Substitute the values into the formula: Perimeter = 2 × (10 cm + 5 cm).
Step 5: Calculate the sum inside the parentheses: 10 cm + 5 cm = 15 cm.
Step 6: Multiply the sum by 2: 2 × 15 cm = 30 cm.
Step 7: Conclude that the perimeter of the rectangle is 30 cm.

Perimeter of a Rectangle – The perimeter is calculated by adding the lengths of all sides, which for a rectangle is given by the formula P = 2(length + width).
