Answer 1

Ответ:

а) 126 : 9 * 2 = 28 (км) — озеленили

126-28 = 98 (км)  

Ответ: 98 км

б) 15 : 5 * 3 = 9 (км) - ширина

(15 + 9) * 2 = 48 (км) - периметр

15 * 9 = 135 (км^2) - площадь

Answer 2

Ответ:

а) 126 : 9 * 2 = 28 (км) — озеленили

126-28 = 98 (км)

Ответ: 98 км

б) 15 : 5 * 3 = 9 (км) - ширина

(15 + 9) * 2 = 48 (км) - периметр

15 * 9 = 135 (км^2) - площадь

Answer 3

Task 1: Length of Road to be Landscaped

The length of the newly constructed road is 126 km. 2/9 of the road has been landscaped. We need to find out how many kilometers of the road are left to be landscaped.

To find the length of the road left to be landscaped, we can use the following calculation: \[ \text{Length of road left to be landscaped} = \text{Total length of road} - \text{Length already landscaped} \]

Using the given values: \[ \text{Length of road left to be landscaped} = 126 \, \text{km} - \left(126 \, \text{km} \times \frac{2}{9}\right) \]

\[ \text{Length of road left to be landscaped} = 126 \, \text{km} - 28 \, \text{km} \]

\[ \text{Length of road left to be landscaped} = 98 \, \text{km} \]

The length of the road left to be landscaped is 98 km.

Task 2: Dimensions and Measurements of a Field

The length of the field is 15 km, and the width is 5 times the length. We need to find the width of the field, as well as calculate the perimeter and area of the field.

To find the width of the field: \[ \text{Width of the field} = 5 \times \text{Length of the field} \]

\[ \text{Width of the field} = 5 \times 15 \, \text{km} \]

\[ \text{Width of the field} = 75 \, \text{km} \]

The width of the field is 75 km.

To find the perimeter of the field: \[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \]

\[ \text{Perimeter} = 2 \times (15 \, \text{km} + 75 \, \text{km}) \]

\[ \text{Perimeter} = 2 \times 90 \, \text{km} \]

\[ \text{Perimeter} = 180 \, \text{km} \]

The perimeter of the field is 180 km.

To find the area of the field: \[ \text{Area} = \text{Length} \times \text{Width} \]

\[ \text{Area} = 15 \, \text{km} \times 75 \, \text{km} \]

\[ \text{Area} = 1125 \, \text{km}^2 \]

The area of the field is 1125 km².
