This 2400 square meter rectangular piece of land is surrounded by a 200 meter long fence.

This 2400 square meter rectangular piece of land is surrounded by a 200 meter long fence. Find the length of this piece.

Since the fence is placed along the perimeter of the entire site, the area of the images is equal to the area of the site, that is, 2400 m ^ 2.
Let’s write down the general formula for finding the area of a rectangle:
S = a * b (where S is the area, a is the length of the rectangle, b is the width of the rectangle).
It is given that the length of the site / fence is 200 meters. Substituting the data into the formula, we can express and find the width of the given rectangle:
S = a * b;
2400 = 200 * X;
X = 2400: 200;
X = 12.
Thus, the width of this section / rectangle is 12 meters.
Answer: the width is 12 meters.
