Question

Найдите площадь и периметр участка , у которого ширина равно 350 м , адлина в 4 раза больше . Выразите площадь в гектарах и арах .

Answer 1

350 (м) - ширина
350 * 4 = 1400 (м) - длина
S = 350 * 1400 = 490000 м² = 49 га = 121 акр
P = 350 + 350 + 1400 + 1400 = 3500 м

Answer 2

Calculation of Area and Perimeter

To find the area and perimeter of a plot with a width of 350 meters and a length 4 times greater, we can follow these steps:

1. Calculate the length of the plot: Since the length is 4 times greater than the width, we can multiply the width by 4 to find the length. - Length = 350 meters * 4 = 1400 meters

2. Calculate the area of the plot: The area of a rectangle is given by the formula A = length * width. - Area = 1400 meters * 350 meters = 490,000 square meters

3. Convert the area to hectares and ares: - 1 hectare = 10,000 square meters - 1 are = 100 square meters

To convert the area from square meters to hectares, we divide the area by 10,000: - Area in hectares = 490,000 square meters / 10,000 = 49 hectares

To convert the area from square meters to ares, we divide the area by 100: - Area in ares = 490,000 square meters / 100 = 4,900 ares

4. Calculate the perimeter of the plot: The perimeter of a rectangle is given by the formula P = 2 * (length + width). - Perimeter = 2 * (1400 meters + 350 meters) = 2 * 1750 meters = 3500 meters

Therefore, the area of the plot is 490,000 square meters, which is equivalent to 49 hectares or 4,900 ares, and the perimeter of the plot is 3500 meters.
