The length of the rectangular section is 200 m, and its width is 77% of the length. 23%

The length of the rectangular section is 200 m, and its width is 77% of the length. 23% of this area is plowed. How much has not been plowed?

1. Determine the width of the site:

200: 100 * 77 = 154 (m).

2. Find the area of the plot using the formula for calculating the area of a rectangle:

P = ab = 200 * 154 = 30800 (m ^ 2).

3. Determine which part of the plot is plowed:

30800: 100 * 23 = 7084 (m ^ 2).

4. Determine what area of the site is not plowed and convert the result into hectares, knowing that 1 hectare contains 10,000 m ^ 2:

(30800 – 7084): 10000 = 23716: 10000 = 2.3716 (ha).

Answer: A part of the plot with an area of 2.3716 ha has not been plowed.
