Question

Длина прямоугольного участка земли 43 м, а его ширина на 15 м меньше длины. Найдите периметр и площадь участка.

Answer 1

Problem Analysis

We are given the length and width of a rectangular piece of land. The length is 43 meters, and the width is 15 meters less than the length. We need to find the perimeter and area of the land.

Calculation

Let's calculate the width of the land first. We are given that the width is 15 meters less than the length, which means the width is 43 - 15 = 28 meters.

Now, we can calculate the perimeter and area of the land.

Perimeter: The perimeter of a rectangle is given by the formula: perimeter = 2 * (length + width).

Substituting the values, we have: perimeter = 2 * (43 + 28) = 2 * 71 = 142 meters.

Area: The area of a rectangle is given by the formula: area = length * width.

Substituting the values, we have: area = 43 * 28 = 1204 square meters.

Therefore, the perimeter of the land is 142 meters, and the area of the land is 1204 square meters.

Answer

The perimeter of the rectangular piece of land is 142 meters, and the area of the land is 1204 square meters.
