The plot is rectangular in shape, the width of which is 135 m. The perimeter of the plot is 900 m. What is the area?

From the condition it is known that we are given a rectangular section, the width of which is 135 meters. The perimeter of the site is 900 meters. For what is the area, we first need to find the length of the rectangle.
Let’s denote the length through the variable x and solve the linear equation. Let’s remember the formula for finding the perimeter:
P = 2 (a + b);
Substitute the known values:
2 (x + 135) = 900;
x + 135 = 450;
x = 450 – 135;
x = 315 meters length of the rectangle.
Let’s move on to finding the area of the rectangle:
S = a * b = 315 * 135 = 42,525 m2 area of the rectangle.
