Question

Ширина клумбы 3 метра а длина на 7 метров больше. Сколько кустов роз аысадили на этой клумбе, если на 1 кв метр высаживали 4 куста

Answer 1

Площадь 30 метров (3+7=10; 10*3=30)
30*4=120
ответ: 120 кустов

Answer 2

Тогда надо:
1)7+3=10-длина
2)10*3=30-площадь
3)30*4=120 кустов
Ответ:120 кустов

Answer 3

I can understand and communicate fluently in your language of choice. You asked me to answer in detail. The width of the flower bed is 3 meters and the length is 7 meters more. How many rose bushes were planted on this flower bed, if 4 bushes were planted per square meter?

To solve this problem, we need to find the area of the flower bed and multiply it by the number of bushes per square meter. The area of a rectangle is given by the formula $$A = lw$$, where $l$ is the length and $w$ is the width. In this case, the width is 3 meters and the length is 7 meters more than the width, so we can write $$l = w + 7$$.

Substituting these values into the formula, we get $$A = (w + 7)w = w^2 + 7w$$.

Plugging in the given value of $w = 3$, we get $$A = 3^2 + 7 \times 3 = 9 + 21 = 30$$.

The area of the flower bed is 30 square meters. To find the number of rose bushes, we multiply the area by the number of bushes per square meter, which is 4. Therefore, the number of rose bushes is $$4 \times 30 = 120$$.

The answer is 120 rose bushes. If you want to learn more about how to take user input and use it in a function in Python, you can check out this [web page](https://stackoverflow.com/questions/37893927/python-how-to-take-user-input-and-use-that-in-function).
