Question

Периметр стадиона имеющего прямоугольную форму равен 1 км длина стадиона 300 метров какова его площадь?

Answer 1

1)P=1км=1000м=(300+x)*2
2)(1000-300*2):2=200(м)-ширина
3)300*200=60000(м)-S                              60000м=60км
Ответ:60км

Answer 2

1)300+300=600(м)-2 длины
2)1000-600=400(м)-2 ширины
3)400/2=200(м)-1ширина
4)200*300=60000(м)
ОТвет:60000м-площадь

Answer 3

Calculating the Area of the Stadium

To find the area of the stadium, we can use the formula:

Area = Length × Width

Given that the perimeter of the stadium is 1 km and the length of the stadium is 300 meters, we can calculate the width of the stadium using the perimeter and the length.

Calculating the Width of the Stadium

To find the width, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 × (Length + Width)

We know the perimeter is 1 km and the length is 300 meters. We can use this information to calculate the width of the stadium.

Calculation

Using the given information, we can calculate the width of the stadium:

Perimeter = 2 × (Length + Width)

1 km = 2 × (300 m + Width)

0.5 km = 300 m + Width

Width = 0.5 km - 300 m

Conversion

Before proceeding with the calculation of the area, we need to convert the width to meters to ensure consistent units.

0.5 km = 500 m

Final Calculation

Now that we have the width in meters, we can calculate the area of the stadium:

Area = Length × Width

Area = 300 m × 500 m

Result

The area of the stadium is 150,000 square meters.

This calculation is based on the given dimensions and the formula for the area of a rectangle.
