Question

Площадь огорода 48 кв.м. Его длина 90 дм.Найди периметр огорода.

Answer 1

B=S/a. Значит b=4800 кв. дм./90дм.=160/3 дм. Значит периметр огорода равен 2*(160/3+90)=286 2/3 дм.

Answer 2

Calculation of Perimeter of the Garden

To find the perimeter of the garden, we need to know the length of each side of the garden. From the given information, we know that the area of the garden is 48 square meters and its length is 90 decimeters.

To calculate the perimeter, we can use the formula P = 2(a + b), where P is the perimeter and a and b are the lengths of the adjacent sides of the garden.

Let's calculate the perimeter using the given information:

1. Convert the length of the garden from decimeters to meters: - 90 decimeters = 9 meters (since 1 decimeter = 0.1 meter).

2. Find the width of the garden using the formula for area: - Area = length × width - 48 square meters = 9 meters × width - Width = 48 square meters / 9 meters = 5.33 meters (rounded to two decimal places).

3. Calculate the perimeter using the formula P = 2(a + b): - P = 2(9 meters + 5.33 meters) - P = 2(14.33 meters) - P = 28.66 meters.

Therefore, the perimeter of the garden is approximately 28.66 meters.
