Question: 1 / 400

If a rectangle has a length of 10 cm and a width of 4 cm, what is its perimeter?

24 cm

26 cm

28 cm

To find the perimeter of a rectangle, the formula used is \( P = 2 \times (length + width) \). In this case, the length is 10 cm and the width is 4 cm.

First, add the length and width together:

\( 10 \, \text{cm} + 4 \, \text{cm} = 14 \, \text{cm} \).

Next, multiply this sum by 2 to find the perimeter:

\( P = 2 \times 14 \, \text{cm} = 28 \, \text{cm} \).

This calculation shows that the perimeter of the rectangle is indeed 28 cm, which is why that answer is correct.
