Find the width of this rectangular piece of land.
According to the condition of the problem, the length of this rectangular piece of land is 450 m, and its width is 50 meters less, therefore, the width of this piece of land is:
450 – 50 = 400 m.
Let us find the area S of a given rectangular section as the product of the length and width of this section:
S = 450 * 400 = 180,000 m².
Let’s express the resulting area in hectares.
In 1 hectare there are 10,000 m2, therefore, the area of this site in hectares will be:
S = 180,000 m² = 180,000/10000 ha = 18 ha.
Answer: the area of this site is 18 hectares.
