Question

Довжина прямокутної ділянки 53 м, а її периметр - 200 м. Чому дорівнює площа такої ділянки? А 7 791 м2 Б 4 982 м2 В 2 491 м2

Answer 1

В) 
1) 53+53=106  м довжини
2) 200-106=94 м ширини
3)94:2=47 м ширина
4)47*53=2491 м2

Answer 2

Calculating the Area of a Rectangular Plot

To find the area of a rectangular plot, we can use the formula: Area = Length × Width.

Given: - Length of the rectangular plot = 53 m - Perimeter of the rectangular plot = 200 m

Solution:

First, let's find the width of the rectangular plot using the given information about the perimeter.

The formula for the perimeter of a rectangle is: Perimeter = 2 × (Length + Width).

We are given that the perimeter is 200 m, and the length is 53 m. We can use this information to solve for the width.

Using the formula for the perimeter: 200 = 2 × (53 + Width)

Solving for the width: 200 = 106 + 2 × Width 94 = 2 × Width Width = 47 m

Now that we have the length and width, we can calculate the area of the rectangular plot: Area = Length × Width Area = 53 m × 47 m Area = 2491 m^2

Answer:

The area of the rectangular plot is 2491 m^2 (В).
