Question

Длина прямо угольного участка равна 27. а ширина на 9м меньше. найди периметр и площадь этого участка

Answer 1

1)27-9=18м-ширина. 2)27*18=486(м.кв.)-площадь 3)(27*2)+(18*2) =90м-периметр

Answer 2

Д-    27 м
Ш-   27-9=18 м
Р=(27+18)*2=90 м
S=27*18=486 м²

Answer 3

Problem Analysis

We are given the length of a rectangular plot as 27 meters and the width as 9 meters less than the length. We need to find the perimeter and area of this plot.

Calculation

Let's calculate the width of the plot first. According to the given information, the width is 9 meters less than the length. So, the width would be 27 - 9 = 18 meters.

Now, we can calculate the perimeter and area of the plot using the formulas:

- Perimeter of a rectangle: P = 2 * (length + width) - Area of a rectangle: A = length * width

Substituting the values, we get:

- Perimeter: P = 2 * (27 + 18) = 2 * 45 = 90 meters - Area: A = 27 * 18 = 486 square meters

Therefore, the perimeter of the plot is 90 meters and the area is 486 square meters.

Answer

The perimeter of the rectangular plot is 90 meters and the area is 486 square meters.
