The length of a rectangular field is 4km 300m, and its width is 1km 600m less.

The length of a rectangular field is 4km 300m, and its width is 1km 600m less. Find the area of the field and its expressiveness in hectares.

First, let’s translate the field length into meters:

4 km 300 m = 4 * 1000 + 300 = 4000 + 300 = 4300 meters.

Now let’s translate into meters:

1 km 600 m = 1 * 1000 + 600 = 1000 + 600 = 1600 meters.

Find out the width of the field. This requires:

4300 m – 1600 m = 2700 m – field width.

Next, we find out the area of the field if we multiply the length by the width. The area will be denoted by the letter S.

S = 4300 m * 2700 m = 11610000 m2.

Now let’s translate the found area into hectares, dividing it by ten thousand:

1,161,000 / 10,000 = 1,161 hectares is the size of the field.
