Find a rectangular garden perimeter. If the sum of the lengths of two different sides of this garden is 80 meters.

We denote the lengths of the sides of this rectangular garden through x and y.

According to the condition of the problem, the sum of the lengths of two different sides of this garden is 80 meters, therefore, we can write the following ratio:

x + y = 80.

Let’s find the perimeter of this garden.

The perimeter of any rectangle is equal to the sum of the length and width of that rectangle times 2.

Since this garden has a rectangular shape, its perimeter P is:

P = 2 * (x + y).

Substituting the value x + y = 80 into this ratio, we get:

P = 2 * 80 = 160 m.

Answer: the perimeter of the garden is 160 m.
