Cevap

The correct area of the label is 2222 square centimeters.
The area of a rectangle is found by multiplying its length by its width. The length of the label is 5.55.5 cm and the width is 4.04.0 cm. Multiplying these together gives 5.5×4.0=225.5 \times 4.0 = 22 square centimeters.

Adım Adım Çözüm

1
Identify the shape and the goal from the word problem.
The shape is a rectangle and the goal is to find its area.
Identifying the shape ensures the correct mathematical formula is applied.
2
Set up the area formula for a rectangle.
Area=length×width\text{Area} = \text{length} \times \text{width}
This is the standard geometric formula for the area of a rectangle.
3
Substitute the given values into the formula and multiply.
Area=5.5×4.0=22\text{Area} = 5.5 \times 4.0 = 22
Multiplying the given dimensions provides the final area in square centimeters.
