Step by Step Solution

Step 1

The picture below shows the rectangle with the length of 5cm and the width of 3cm.

Step 2

To calculate the area, we can use the formula for the area of a rectangle:

Step 3

Since the length is given as 5cm, we can substitute l with 5. Similarly, since the width is given as 3cm, we can substitute w with 3. After doing so, we can calculate for A, as shown below:

Step 4

Now, the calculated number 15 only has a meaning if we include the unit for it. Since the given length and width are in cm, the unit for area will be cm^{2}. Hence:
