Question

Длина поля прямоугольной формы 40 м,это в 2 раза больше,чем ширина.Узнайте площадь и периметр поля?

Answer 1

Здесь , это, (то есть 40 ) в два раза больше чем ширина . Получается длинна 40 и ширина 20.
S=ab S =40×20=800 см ^2
P=2 (40+20) =120 см.

Answer 2

40:2=20 м ширина поля
20*40=800 м2 площадь поля
2*(20+40)=2*60=120 м периметр поля

Answer 3

Problem Analysis

We are given that the length of a rectangular field is 40 m, which is twice the width of the field. We need to find the area and perimeter of the field.

Solution

Let's denote the width of the field as w. According to the given information, the length of the field is twice the width, so we can write:

Length = 2 * Width

Substituting the given length value of 40 m, we can solve for the width:

40 m = 2 * Width

Dividing both sides of the equation by 2, we get:

Width = 40 m / 2 = 20 m

Now that we have the width, we can calculate the area and perimeter of the field.

Calculating the Area

The area of a rectangle is given by the formula:

Area = Length * Width

Substituting the values, we have:

Area = 40 m * 20 m = 800 square meters

Therefore, the area of the field is 800 square meters.

Calculating the Perimeter

The perimeter of a rectangle is given by the formula:

Perimeter = 2 * (Length + Width)

Substituting the values, we have:

Perimeter = 2 * (40 m + 20 m) = 2 * 60 m = 120 meters

Therefore, the perimeter of the field is 120 meters.

Summary

- The area of the rectangular field is 800 square meters. - The perimeter of the rectangular field is 120 meters.
