Question

Длина пастбища прямоугольной формы равна 580 метров а ширина 250 метров Вычисли площадь пастбища (в гектарах) и его периметр (в километрах)

Answer 1

580*250=145000 = 14,5 га

2*(580+250)=1660 м = 1,66 км

Answer 2

Calculation of the Area and Perimeter of the Pasture

To calculate the area and perimeter of a rectangular pasture with a length of 580 meters and a width of 250 meters, we can use the following formulas:

1. Area of a rectangle: Area = length × width 2. Perimeter of a rectangle: Perimeter = 2 × (length + width)

Let's calculate the area and perimeter using these formulas.

Calculation:

1. Area of the pasture: - Length = 580 meters - Width = 250 meters

Using the formula Area = length × width, we can calculate the area as follows:

Area = 580 meters × 250 meters = 145,000 square meters

Therefore, the area of the pasture is 145,000 square meters.

2. Perimeter of the pasture: - Length = 580 meters - Width = 250 meters

Using the formula Perimeter = 2 × (length + width), we can calculate the perimeter as follows:

Perimeter = 2 × (580 meters + 250 meters) = 2 × 830 meters = 1,660 meters

Therefore, the perimeter of the pasture is 1,660 meters.

Conversion to Hectares and Kilometers:

To convert the area from square meters to hectares and the perimeter from meters to kilometers, we can use the following conversion factors:

1 hectare = 10,000 square meters 1 kilometer = 1,000 meters

1. Area in hectares: - Area = 145,000 square meters

To convert square meters to hectares, we divide the area by 10,000:

Area in hectares = 145,000 square meters / 10,000 = 14.5 hectares

Therefore, the area of the pasture is 14.5 hectares.

2. Perimeter in kilometers: - Perimeter = 1,660 meters

To convert meters to kilometers, we divide the perimeter by 1,000:

Perimeter in kilometers = 1,660 meters / 1,000 = 1.66 kilometers

Therefore, the perimeter of the pasture is 1.66 kilometers.

So, the area of the pasture is 14.5 hectares and its perimeter is 1.66 kilometers.

Please note that the calculations provided above are based on the given dimensions of the pasture and the formulas for calculating the area and perimeter of a rectangle.
