If a rectangle has a width of 5 cm and a length of 8 cm, what is its perimeter?

To find the perimeter of a rectangle, the formula is used:

Perimeter = 2 * (Length + Width).

In this case, the rectangle has a length of 8 cm and a width of 5 cm. First, you add the length and width together:

8 cm + 5 cm = 13 cm.

Now, you multiply this sum by 2 to find the perimeter:

2 * 13 cm = 26 cm.

Thus, the perimeter of the rectangle is 26 cm. This confirms why the correct answer is the choice indicating a perimeter of 26 cm, as it accurately reflects the calculation based on the given dimensions of the rectangle.
