Question

Длина сада прямоугольной формы 30 метров на изготовление забора вокруг сада потребовалось 100 метров сетки Найти ширину этого сада

Answer 1

Рпр = 2(А+В) ; 1) А = 2*30=60м ; В) = (100м -60м) : 2 =40:2 = 20м.        Ответ: ширина сада = 20м.

Answer 2

Finding the Width of the Garden

To find the width of the rectangular garden, we can use the information provided about the length of the garden and the amount of fencing required.

According to the information given, the length of the garden is 30 meters, and it took 100 meters of fencing to surround the garden with a fence.

To find the width, we can subtract twice the length from the total amount of fencing. This is because the fence goes around the perimeter of the garden, so we need to subtract the length twice (once for each side of the garden).

Let's calculate the width:

Total amount of fencing = 100 meters Length of the garden = 30 meters

Width of the garden = (Total amount of fencing - 2 * Length of the garden)

Width of the garden = (100 - 2 * 30) meters

Width of the garden = 40 meters

Therefore, the width of the garden is 40 meters.
