Find the area of a rectangle if its width is 4 km 300 m and its length is 5 times greater.

To solve the problem, you first need to determine the length of the rectangle.

Since the condition for the problem indicates that it is 5 times its width, then this requires multiplying its width by 5.

For the convenience of the solution, we translate the width in km.

4 km 300 m = 4.3 km.

4.3 * 5 = 21.5 km or 21 kilometers 500 meters.

In order to determine the area of a rectangle, you need to multiply its width by its length.

In this case, we get:

4.3 * 21.5 = 92.45 square kilometers.

Answer: The area is 92.45 km ^ 2.
