Find the length of a rectangular area if its width is 150 and the area is 3 hectares.

The formula for finding the area of a rectangle:
S = a * b, where a is the width, b is the length of the rectangle.

From this formula, we express the length of the rectangle:

b = S: a.

1) We translate the area of the site in m ^ 2:

3 hectares = 30,000 m ^ 2.

2) Find the length of the section:

30,000: 150 = 200 (m) – section length.

Answer: the length of the rectangular section is 200 meters.
