If a rectangle has a length of 15 cm and a width of 10 cm, what is its perimeter? (2022)
Step 1: Identify the length of the rectangle, which is 15 cm.
Step 2: Identify the width of the rectangle, which is 10 cm.
Step 3: Add the length and width together: 15 cm + 10 cm.
Step 4: Calculate the sum: 15 + 10 = 25 cm.
Step 5: Multiply the sum by 2 to find the perimeter: 2 * 25 cm.
Step 6: Calculate the final result: 2 * 25 = 50 cm.
Perimeter of a Rectangle – The perimeter of a rectangle is calculated by adding the lengths of all sides, which can be simplified to the formula P = 2(length + width).
