Question

Длина игровой площадки 18м, а ширина составляет одну шестую часть длины. Сколько мотков по 7м проволоки понадобится, чтобы огородить эту площадку двойным слоем проволоки?

Answer 1

18 \ 6 * 1 = 3 м - ширина участка
(18 + 3) * 2 = 42 м - периметр участка
42 * 2 \ 7 = 12 мотков понадобится 

Answer 2

Calculating the Amount of Wire Needed to Fence the Playground

To calculate the amount of wire needed to fence the playground with a double layer of wire, we can follow these steps:

1. Calculate the Perimeter of the Playground: - The length of the playground is 18m, and the width is one-sixth of the length.

2. Calculate the Width of the Playground: - Width = 1/6 * Length

3. Calculate the Perimeter: - Perimeter = 2 * (Length + Width)

4. Calculate the Total Length of Wire Needed: - Total Length of Wire = Perimeter * 2

Calculation

1. Calculate the Width of the Playground: - Width = 1/6 * 18m - Width = 3m

2. Calculate the Perimeter: - Perimeter = 2 * (18m + 3m) - Perimeter = 2 * 21m - Perimeter = 42m

3. Calculate the Total Length of Wire Needed: - Total Length of Wire = 42m * 2 - Total Length of Wire = 84m

Conclusion

To fence the playground with a double layer of wire, 84 meters of wire will be needed.
