If a rectangle has an area of 24 cm² and a width of 4 cm, what is its length?

Step 1: Understand that the area of a rectangle is calculated by multiplying its length by its width.
Step 2: Write down the formula for area: Area = Length × Width.
Step 3: We know the area is 24 cm² and the width is 4 cm.
Step 4: Substitute the known values into the formula: 24 cm² = Length × 4 cm.
Step 5: To find the length, we need to isolate it. We can do this by dividing both sides of the equation by 4 cm.
Step 6: Perform the division: Length = 24 cm² ÷ 4 cm.
Step 7: Calculate the result: Length = 6 cm.
