In order to find a part of a whole, it is necessary to divide this value by the denominator of the fraction and multiply by its numerator.
The width is 4/8 (we will shorten: 1/2) the length equal to 1600 m:
1600: 2 * 1 = 800 m.
The area of a rectangular area with such measurements is calculated by the formula:
S = a * b = 1600 * 800 = 1280000 m2 = 128 hectares, since 1 hectare = 10000 m2.
