The area of a rectangular piece of land is 63 m2, width 7 m. Calculate the length of the section. Find its perimeter.

Since the area of the rectangle is calculated by the formula: S = ab, then b = S: a. We supply the values from the problem: b = 63: 7 = 9 m (section length). To find the perimeter of a rectangle, you need to apply the formula: P = 2 (a + b), where a and b are the sides of the rectangle. P = 2 (7 + 9) = 2 * 16 = 32 meters perimeter of the rectangular section.
