Final answer:
To find the width of the rectangle, we can divide the area by the length.
Step-by-step explanation:
The area of a rectangle is found by multiplying its length and width. In this case, the area is given as 10 cm². We can assume that the length and width are both in centimeters since they are not specified otherwise.
Let's assume the width of the rectangle is r cm. To find the length, we can divide the area by the width: length = 10 cm² / r cm = 10/r cm. Since the area is given as 10 cm², we can write the equation:
10 cm² = r cm * (10/r cm)
10 cm² = 10 cm
We can cancel out the units cm and solve for r:
10 = r
Therefore, r = 10 cm.
