If a rectangle has a length of 12 cm and a width of 4 cm, what is its perimeter? (2019)
Step 1: Identify the length of the rectangle, which is 12 cm.
Step 2: Identify the width of the rectangle, which is 4 cm.
Step 3: Add the length and width together: 12 cm + 4 cm = 16 cm.
Step 4: Multiply the sum by 2 to find the perimeter: 2 * 16 cm = 32 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).
