What is the perimeter of a rectangle with a length of 10 units and a width of 5 units?

15 units

20 units

30 units

25 units

To find the perimeter of a rectangle, you can use the formula:

Perimeter = 2 * (length + width).

For a rectangle with a length of 10 units and a width of 5 units, you would first add the length and the width:

10 units + 5 units = 15 units.

Next, you would multiply that sum by 2 to find the perimeter:

2 * 15 units = 30 units.

Thus, the perimeter of the rectangle is 30 units. This makes the correct answer the option representing 30 units. The incorrect options stem from miscalculations, such as not properly applying the perimeter formula or mistakenly calculating the sum of the length and width.
