The length of the rectangle of the plot of land is 8 m, and the width is 2 times less than the length.

The length of the rectangle of the plot of land is 8 m, and the width is 2 times less than the length. What is the area of the plot? How long is the border of this section?  

Length (a) = 8 m;
Width (b) =? m, 2 times less than a;

Such -? m ^ 2;

Ruch -? m.

First, we find the width of the site (b): b = 8: 2 = 4 (m);

Because by condition, the plot of land is rectangular, then its area is found by the formula: Such = a * b = 8 * 4 = 32 (m ^ 2).

The length of the border of the site is its perimeter, which we find by the formula: Puch = (a + b) * 2 = (8 + 4) * 2 = 24 (m).

Answer: the area of the site is 32 cm ^ 2, and the length of its border is 24 m.
