Question

Участок прямоугольной формы с трех сторон обнесен забором общая длина которого 170 м вдоль одной из коротких сторон высаженной живая изгородь длиной 40 метров Вычисли площадь участка

Answer 1

(170+40)×2=420м площадь

Answer 2

Calculation of the Area of the Plot

To calculate the area of the rectangular plot, we need to know the lengths of its sides. From the given information, we know that three sides of the plot are enclosed by a fence with a total length of 170 meters. Additionally, there is a living hedge planted along one of the shorter sides, which has a length of 40 meters.

Let's denote the lengths of the other two sides as x and y. Since the plot is rectangular, the length of the side opposite the hedge is also 40 meters.

To find the remaining side length, we can subtract the lengths of the known sides from the total fence length:

x + 40 + y = 170

Simplifying the equation, we have:

x + y = 130

Now we have two equations:

1. x + y = 130 2. x = 40

We can solve this system of equations to find the values of x and y.

Substituting the value of x from equation 2 into equation 1, we get:

40 + y = 130

Simplifying, we find:

y = 90

Therefore, the lengths of the sides of the rectangular plot are 40 meters and 90 meters.

To calculate the area of the plot, we multiply the lengths of the sides:

Area = x * y = 40 * 90 = 3600 square meters

So, the area of the rectangular plot is 3600 square meters.
