Question

Периметр участка прямоугольной формы 400м. Длина участка в 1,5 раза больше ширины. Какой урожай соберут с этого участка, если с одного ара собирают 0,8m помидоров? ( 1ар = 100м2 )

Answer 1

1) 400 : 2 = 200 ( м ) сумма длины и ширины
2) 200 : ( 1,5 + 1 ) = 200 : 2,5 = 80 ( м ) ширина
3) 1,5 • 80 = 120 ( м ) длина
4) 80 • 120 = 9600 ( м2 ) = 96 ( ар )
5) 0,8m • 96 = 76,8m ( помидоров )
Ответ 76,8m помидоров

Answer 2

Длина - 1,5х
ширина -х
2*(1,5х+х)=400
2*2,5х=400
2,5х=200
х=80 (м) - ширина
80*1,5 = 120(м) - длина
80*120=9600 (кв.м) = 96 (ар) - площадь
96*0,8=76,8 - всего помидор соберут с участка

Answer 3

Calculation of Perimeter:

To calculate the perimeter of a rectangular plot, we need to know the length and width of the plot. In this case, we are given that the perimeter of the plot is 400m and the length of the plot is 1.5 times the width.

Let's assume the width of the plot is x meters. Therefore, the length of the plot would be 1.5x meters.

The formula to calculate the perimeter of a rectangle is: Perimeter = 2(length + width).

Substituting the given values, we can write the equation as:

400 = 2(1.5x + x).

Simplifying the equation, we get:

400 = 2(2.5x).

Dividing both sides of the equation by 2, we have:

200 = 2.5x.

Now, we can solve for x:

x = 200 / 2.5.

Evaluating the expression, we find:

x = 80.

Therefore, the width of the plot is 80 meters and the length is 1.5 times the width, which is 120 meters.

Calculation of Crop Yield:

To calculate the crop yield, we need to know the area of the plot and the yield per unit area. In this case, we are given that 1 ar (100m²) yields 0.8m of tomatoes.

The area of the plot can be calculated by multiplying the length and width of the plot. In this case, the length is 120 meters and the width is 80 meters.

Therefore, the area of the plot is:

Area = length × width = 120m × 80m.

Calculating the area, we find:

Area = 9600m².

Now, we can calculate the crop yield:

Crop Yield = Area × Yield per unit area.

Substituting the values, we have:

Crop Yield = 9600m² × 0.8m/100m².

Simplifying the expression, we get:

Crop Yield = 76.8m.

Therefore, the crop yield from this plot would be 76.8 meters of tomatoes.

Please note that these calculations are based on the given information and assumptions.
