Final answer:
The minimum and maximum possible areas of a rectangle measuring 6 km by 11 km are both 66 km².
Step-by-step explanation:
To find the minimum possible area of the rectangle, we use the formula A = l x w, where A is the area, l is the length, and w is the width of the rectangle. In this case, l = 6 km and w = 11 km. Substituting these values into the formula, we get A = 6 km x 11 km = 66 km2.
To find the maximum possible area of the rectangle, we use the same formula with the dimensions reversed, so l = 11 km and w = 6 km. Substituting these values into the formula, we get A = 11 km x 6 km = 66 km2.
Therefore, the minimum and maximum possible areas of the rectangle measuring 6 km by 11 km are both 66 km2.
