Question

Ширина земельного участка прямоугольной формы 7 М. Найди периметр этого участка, если его площадь 91м2

Answer 1

Длина=91/7=13м
Р=(13+7)*2=40м

Answer 2

Calculation of Perimeter

To find the perimeter of a rectangular land plot, we need to know the length and width of the plot. In this case, we are given that the land plot has a rectangular shape with a width of 7 meters and an area of 91 square meters.

To calculate the length of the land plot, we can use the formula for the area of a rectangle:

Area = Length × Width

Given that the area is 91 square meters and the width is 7 meters, we can rearrange the formula to solve for the length:

Length = Area / Width

Substituting the given values, we get:

Length = 91 / 7

Calculating this, we find that the length of the land plot is approximately 13 meters.

Now that we have both the length and width of the land plot, we can calculate the perimeter using the formula:

Perimeter = 2 × (Length + Width)

Substituting the values we have, we get:

Perimeter = 2 × (13 + 7)

Calculating this, we find that the perimeter of the land plot is approximately 40 meters.

Therefore, the perimeter of the rectangular land plot with a width of 7 meters and an area of 91 square meters is approximately 40 meters.
