Final answer:
The area of a rectangle is calculated by multiplying its length by its width, and in this case, the area is given as 0.4 m². There are multiple combinations of length and width that satisfy this condition.
Step-by-step explanation:
The area of a rectangle is calculated by multiplying its length by its width.
In this case, we are given the area of the rectangle as 0.4 m². Since the area is given to a tenth of a square meter, we will round it to 0.4 m².
So, to find the length and width of the rectangle, we can use the fact that multiplying them together gives us 0.4 m².
For example, if the length of the rectangle is 0.2 m and the width is 2 m, multiplying them together gives a product of 0.4 m².
Therefore, there are multiple combinations of length and width that satisfy the condition, such as a length of 0.4 m and a width of 1 m, or a length of 0.1 m and a width of 4 m.
