Question

Знайти периметр прямокутника площа якого дорівнює 14,35 м,кв а довжина3,5м

Answer 1

Ответ:

ширина = 14,35÷3,5=4,1м

периметр = (3,5×2)+(4,1×2)=15,2м

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, you can use the formula:

Perimeter = 2 * (length + width)

Given that the area of the rectangle is 14.35 square meters and the length is 3.5 meters, we can calculate the width of the rectangle using the area and then find the perimeter.

Calculating the Width of the Rectangle

First, let's calculate the width of the rectangle using the given area and length.

The formula for the area of a rectangle is: Area = length * width

We can rearrange this formula to solve for the width: width = Area / length

Substituting the given values: width = 14.35 / 3.5

Calculating the width: width = 4.1 meters

Calculating the Perimeter

Now that we have the length and width of the rectangle, we can use the formula for the perimeter to find the answer.

Using the formula: Perimeter = 2 * (length + width)

Substituting the given values: Perimeter = 2 * (3.5 + 4.1) Perimeter = 2 * 7.6 Perimeter = 15.2 meters

Therefore, the perimeter of the rectangle with an area of 14.35 square meters and a length of 3.5 meters is 15.2 meters.
