Question

1.Найдите периметр земельного участка если длина его равна 6 м 5 см а ширина на 8 дм 290 мм меньше 2. потолок имеет длину 120 дм а ширину на 4м меньше длины найдите площать поталка

Answer 1

6м 5 см--это 605 см.     8 дм 290мм  --это109 см   Ширина участка   605см-109см=496см или 4м 96 см     Периметр участка =( 6м5см + 4 м96 см) * 2=11.01 *2= 22м 2см                                                                                                   2)  120дм=12м.  ширина потолка 12м-4м=8м       Площадь потолка:        12 *8=96 кв. м

Answer 2

Perimeter of the Land Plot

To find the perimeter of a land plot, we need to add up the lengths of all its sides.

The given length of the land plot is 6 meters and 5 centimeters, and the width is 8 decimeters and 290 millimeters less than that.

Let's convert the measurements to a consistent unit before calculating the perimeter.

1 meter = 10 decimeters 1 meter = 100 centimeters 1 meter = 1000 millimeters

So, the length of the land plot is 6 meters and 5 centimeters, which is equivalent to 65 decimeters and 650 centimeters.

The width is 8 decimeters and 290 millimeters less than the length. Let's calculate the width:

Width = Length - 8 decimeters - 290 millimeters

Converting 290 millimeters to decimeters, we get:

290 millimeters = 29 decimeters

Therefore, the width is:

Width = 65 decimeters - 8 decimeters - 29 decimeters = 28 decimeters

Now, we can calculate the perimeter:

Perimeter = 2 * (Length + Width)

Substituting the values:

Perimeter = 2 * (65 decimeters + 28 decimeters) = 2 * 93 decimeters = 186 decimeters

Therefore, the perimeter of the land plot is 186 decimeters.
