Question

Ширина сада 20 м ,а длинна в 3 раза больше. Узнайте Площадь и периметр сада.

Answer 1

1)20х3=60(м)-длина сада.
2)(20+60)х2=160(м)-периметр.
3)20х60=1200(м)
Ответ:периметр сада 160 м,площадь сада 1200 м.

Удачи!:)

Answer 2

Длина = 20 * 3 = 60 
S = 20 * 60 = 1200 
P = 20*2 + 60*2 = 40 + 120 = 160

Answer 3

Calculation of the Area and Perimeter of the Garden

To calculate the area and perimeter of the garden, we need to know the width and length of the garden. According to the given information, the width of the garden is 20 meters, and the length is 3 times greater than the width.

Let's calculate the area and perimeter using this information.

Width of the garden: 20 meters Length of the garden: 3 times the width = 3 * 20 = 60 meters

Calculation of the Area:

The area of a rectangle can be calculated by multiplying its length by its width. In this case, the area of the garden is the product of the length and width.

Area of the garden: Length * Width = 60 * 20 = 1200 square meters

Calculation of the Perimeter:

The perimeter of a rectangle can be calculated by adding the lengths of all its sides. In this case, the perimeter of the garden is the sum of twice the length and twice the width.

Perimeter of the garden: 2 * (Length + Width) = 2 * (60 + 20) = 2 * 80 = 160 meters

Therefore, the area of the garden is 1200 square meters and the perimeter of the garden is 160 meters.
