Final answer:
The area of rectangle ABCD cannot be determined without knowing the length. The range of possible areas depends on the estimated width and the unknown length of the rectangle.
Step-by-step explanation:
The area of a rectangle can be found by multiplying its length by its width. In this case, we are not given the dimensions of rectangle ABCD, so we cannot calculate its exact area. However, we are given a range for the width of the rectangle, from 1.0 cm to 2.0 cm. We are also provided with an estimated width of 1.25 cm, rounded to three significant figures.
Using this estimated width, we can calculate a range of possible areas for the rectangle. If we use the maximum width of 2.0 cm, we get an area of 2.0 cm x length. If we use the estimated width of 1.25 cm, we get an area of 1.25 cm x length. Therefore, the area of rectangle ABCD could be anywhere between 2.0 cm x length and 1.25 cm x length.
