Question

Марина хочет сделать цветочную клумбу в форме параллелограмма. У неё есть 17,8 метра декоративного заборчика. Какой длины должна быть вторая сторона клумбы, если одна сторона равна 2,8 м Ответ: длина второй стороны должна быть не больше {.....}м

Answer 1

Две стороны параллерограмма равны по 2,8м. Две другие стороны равны по (17,8-2,8-2,8):2=6,1 м; ответ: не больше 6,1 м

Answer 2

Calculation of the Length of the Second Side of the Flower Bed

To calculate the length of the second side of the flower bed in the shape of a parallelogram, we need to use the given information.

The first side of the flower bed is given as 2.8 meters. Let's denote this as a = 2.8 meters.

The total length of the decorative fence is given as 17.8 meters. This includes both sides of the flower bed. Since a parallelogram has opposite sides of equal length, we can calculate the length of the second side by subtracting the length of the first side from the total length of the fence.

Let's denote the length of the second side as b.

The equation to calculate the length of the second side is as follows:

a + b + a + b = total length of the fence

Substituting the given values:

2.8 + b + 2.8 + b = 17.8

Simplifying the equation:

2b + 5.6 = 17.8

2b = 17.8 - 5.6

2b = 12.2

b = 12.2 / 2

b = 6.1

Therefore, the length of the second side of the flower bed should be 6.1 meters.
