In the image, the given rectangle has the following dimensions:

• Length = 5.7 cm
• Width = 3 cm

To calculate the area of a rectangle, we use the formula:

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

Substituting the given values:

$\text{Area} = 5.7 \, \text{cm} \times 3 \, \text{cm} = 17.1 \, \text{cm}^2$

Thus, the area of the rectangle is 17.1 cm².

Here are some related questions to expand on this concept:

1. What is the perimeter of this rectangle?
2. How would the area change if the length were doubled?
3. What is the area of a square with the same side length as the width of this rectangle?
4. How would you calculate the area of a triangle with the same base and height as this rectangle?
5. If the dimensions were given in meters, what would the area be in square meters?

Tip: Always remember to keep units consistent when calculating area or any other measurement!
