Question

Прямоугольный участок, длина которого 90 м, а ширина составляет 2/3 длины, обнесен забором из метеллической сетки, высотой 1,6м. Найдите площадь металлической сетки. Помогите!!!!!!!!!!!!!!!!!!!! Очень Срочно!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

1) 90*2/3 = 60 (м)- ширина.

2) (90+60)*2 = 300 (м)- периметр, длина металлической сетки.

3) 300*1,6 = 480 (кв.м)- площадь металлич. сетки.

Ответ: 480 кв. м площадь металлической сетки. 

Answer 2

90*2/3=60 это ширена участка.

 

Теперь узнаем площадь одной стороны забора расположеного по ширене:

 

60*1,6=96 метров квадратных

96*2=192 метра квадратных

 

По длинне:

 

90*1,6=144 метра квадратных

144*2=288 метра квадратных

 

Площадь металической сетки:

 

192+288=480 метров квадратных

Answer 3

To find the area of the metal mesh fence surrounding the rectangular plot, we need to calculate the perimeter of the plot and then multiply it by the height of the fence.

Calculating the Perimeter of the Rectangular Plot:

The length of the plot is given as 90 meters, and the width is 2/3 of the length. To find the width, we can multiply the length by 2/3.

Width = (2/3) * Length = (2/3) * 90 = 60 meters

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we have two sides of length 90 meters and two sides of length 60 meters.

Perimeter = 2 * (Length + Width) = 2 * (90 + 60) = 2 * 150 = 300 meters

Calculating the Area of the Metal Mesh Fence:

The height of the metal mesh fence is given as 1.6 meters. To find the area of the fence, we need to multiply the perimeter of the plot by the height of the fence.

Area of Metal Mesh Fence = Perimeter * Height = 300 * 1.6 = 480 square meters

Therefore, the area of the metal mesh fence is 480 square meters.

Please note that the calculations provided above are based on the information given in the question.
