It is known from the condition that the area of the rectangular land plot is 80 hectares, and the length of the plot is 2 km. In order to find the perimeter of a rectangular land plot, we need to know its width.
To do this, we will use the formula for finding the area of a rectangle.
S = a * b;
Let’s translate hectares into km2, it is known that 1 hectare = 0.01 km2.
80 * 0.01 = 0.8 km2.
0.8 = 2 * b;
b = 0.8: 2;
b = 0.4 km section width.
We are looking for the perimeter by the formula:
P = 2 (a + b) = 2 (2 + 0.4) = 2 * 2.4 = 4.8 km perimeter of the rectangle.
Answer: 4.8 km.
