# The length of the rectangular section is 32m. The side of another phase of the green is square 160dm

The length of the rectangular section is 32m. The side of another phase of the green is square 160dm. Calculate how many meters of wire mesh you need to enclose each section if it is known that they have equal areas.

First of all, we find the area of a square-shaped plot of land, according to the formula:

S = a².

The side length is 160 dm = 16 m. Since 1 m = 10 dm.

S = 16² = 256 m².

Let us express the length of another section, in the form of a rectangle with the same S, and length = 32 m, from the formula:

S = a * b, therefore:

a = S: b = 256: 32 = 8 m.

The grid for each section is installed around the perimeter. Let’s find its length for each section:

P rectangular section = 2a + 2b = 2 * 32 + 2 * 8 = 64 + 16 = 80 m.

R quad. plot = 4a = 4 * 16 = 64 m. One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
