Question

кака найти ширину и площадь есле известна длина и периметр.Длина равна 671м а периметр равен 1408м.

Answer 1

P=2(a+b) 1408=2(a+b). следовательно, а+b=1408:2=704 a=671, следовательно, b=704-671=33 S=ab=22143

Answer 2

Периметр это сумма длин сторон Чтоб найти ширину площади, мы
(1408-671*2)/2=(1408-1342)/2=33(м)
Площадь находим по формуле
671*33=22143(м2)

Answer 3

Finding the Width and Area Given the Length and Perimeter

To find the width and area when the length and perimeter are known, we can use the following steps:

1. Understand the problem: We are given the length and perimeter of a shape and we need to find the width and area.

2. Identify the formula: We can use the formulas for perimeter and area to solve the problem. The perimeter of a shape is the sum of all its sides, while the area is the measure of the space inside the shape.

3. Apply the formulas: Let's apply the formulas to find the width and area.

- Formula for perimeter: Perimeter = 2 * (Length + Width) - Formula for area: Area = Length * Width

4. Solve the problem: Given that the length is 671m and the perimeter is 1408m, we can substitute these values into the formulas to find the width and area.

- From the perimeter formula: 1408 = 2 * (671 + Width) Solving for Width: Width = (1408 - 2 * 671) / 2 = 66m

- From the area formula: Area = 671 * 66 = 44,286 square meters

Therefore, the width is 66 meters and the area is 44,286 square meters.
