Question

Участок прямоугольной формы Ширина которого в 2 раза меньше длины засеяли овсом периметр участка 1140 метров 1 2 убрали комбайном Сколько квадратных метров

Answer 1

Если вопрос сколько квадратных метров осталось то ответ
36 100
я 1140 ÷ 2 = 570
и способом подбора выбираем нужные числа так что бы ширина была меньше в 2 раза
это числа 190 и 380
проверяем
190 + 380 = 570
190 × 2 = 380
значит все правельно
и мы
190 × 380 = 72200 м кв
72200÷2=36100 м кв
осталось

Answer 2

Calculating the Area of the Rectangular Plot

To calculate the area of the rectangular plot, we can use the information provided about its dimensions and perimeter.

Given: - The width of the plot is 2 times smaller than its length. - The perimeter of the plot is 1140 meters. - 1/2 of the plot was harvested by a combine harvester.

Calculations

Let's denote the length of the plot as L and the width as W.

We know that the perimeter of a rectangle is given by the formula: Perimeter = 2(L + W)

Given that the width is 2 times smaller than the length, we can express the width in terms of the length: W = L/2

Substitute the expression for the width into the perimeter formula: 1140 = 2(L + L/2)

Solving for L: 1140 = 2(3/2)L L = 380 meters

Substitute the value of L back into the expression for the width: W = 380/2 W = 190 meters

Now, we can calculate the area of the entire plot: Area = Length × Width Area = 380 × 190 Area = 72200 square meters

Finally, to find the area of the harvested portion, we can calculate half of the total area: Harvested Area = 1/2 × Area Harvested Area = 1/2 × 72200 Harvested Area = 36100 square meters

So, the area of the rectangular plot is 72200 square meters, and the area harvested by the combine harvester is 36100 square meters.
