Question

Площадь прямоугольного футбольного поля равна 66 акров,а ширина поля 60 м.Найдите периметр поля.Сколько килограммов семян газонной смеси понадобится,чтобы засеять это поле, если на 1 кв.м уходит 5 гр семян?

Answer 1

66а=6600 м2

1)6600:60=110м-длина.

2)2*(110+60)=340м-периметр поля.

3)6600*5=33000г=33кг семян-понадобится.

Answer 2

Calculation of the Perimeter of the Football Field

To find the perimeter of the rectangular football field, we need to know the length and width of the field. In this case, the width of the field is given as 60 meters. However, the length of the field is not provided in the question.

Since the area of the field is given as 66 acres, we can use this information to find the length of the field.

To convert acres to square meters, we can use the conversion factor: 1 acre = 4046.86 square meters.

Let's calculate the length of the field first:

Step 1: Convert the area from acres to square meters: 66 acres * 4046.86 square meters/acre = 266,716.76 square meters.

Step 2: Use the formula for the area of a rectangle to find the length: Area = Length * Width 266,716.76 square meters = Length * 60 meters

Step 3: Solve for the length: Length = 266,716.76 square meters / 60 meters = 4,445.28 meters.

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

Step 4: Calculate the perimeter: Perimeter = 2 * (Length + Width) Perimeter = 2 * (4,445.28 meters + 60 meters) Perimeter = 2 * 4,505.28 meters Perimeter = 9,010.56 meters.

Therefore, the perimeter of the football field is approximately 9,010.56 meters.

Calculation of the Amount of Grass Seed Needed

To calculate the amount of grass seed needed to seed the field, we need to know the area of the field and the amount of seed required per square meter.

The area of the field is given as 66 acres, which we have already converted to square meters (266,716.76 square meters).

The amount of seed required per square meter is given as 5 grams.

Step 1: Multiply the area of the field by the amount of seed required per square meter: Amount of seed = 266,716.76 square meters * 5 grams/square meter = 1,333,583.8 grams.

Step 2: Convert grams to kilograms: 1,333,583.8 grams = 1,333.5838 kilograms.

Therefore, approximately 1,333.5838 kilograms of grass seed will be needed to seed the football field.

Please note that these calculations are based on the information provided in the question and may vary depending on the specific requirements and conditions of the field.
