The area of a rectangle is calculated using the formula:

$\text{Area} = \text{Width} \times \text{Length}$

Given:

• Width = 3.1 cm
• Length = 4.4 cm

Calculating the area:

$\text{Area} = 3.1 \, \text{cm} \times 4.4 \, \text{cm} = 13.64 \, \text{cm}^2$

Thus, the area of the rectangle is 13.64 cm².

Here are five related questions for further practice:

1. What is the perimeter of the same rectangle?
2. How would the area change if the width were doubled?
3. What is the area of a rectangle with a width of 5 cm and a length of 7 cm?
4. How do you calculate the area of a square, and how is it different from a rectangle?
5. If a rectangle has an area of 20 cm² and a width of 5 cm, what is its length?

Tip: When calculating the area of any shape, always ensure that all dimensions are in the same units.
