If a rectangle has dimensions of 10 units by 4 units, what is the perimeter?

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

Perimeter = 2 * (length + width)

In this case, the length is 10 units and the width is 4 units. Plugging those values into the formula gives:

Perimeter = 2 * (10 + 4)

= 2 * 14

= 28 units

Thus, the correct answer, which is 28 units, reflects the total distance around the rectangle, confirming the accurate application of the perimeter formula for a rectangle.
