Question

Комната в длину на 30дм больше, ЧЕМ В ШИРИНУ. КАКОВА ПЛОЩАДЬ КОМНАТЫ, если её длина равна 6 метров 70 сантиметров? помогите пожалуйста!

Answer 1

Переведем дм в м 30 дм=3м
6,7м - 3м = 3,7 м (ширина комнаты)
S= 6,7*3,7
S= 24,79
Площадь равна 24,79 метров квадратных

Answer 2

Calculation of the Room's Area

To calculate the area of the room, we need to know the length and width of the room. According to the given information, the length of the room is 6 meters and 70 centimeters, and the length is 30 decimeters (dm) more than the width.

Let's first convert the length of the room to decimeters (dm). Since 1 meter is equal to 10 decimeters, we can calculate the length in decimeters as follows:

Length in decimeters = 6 meters * 10 decimeters/meter + 70 centimeters * 1 decimeter/10 centimeters

Length in decimeters = 60 decimeters + 7 decimeters

Length in decimeters = 67 decimeters

Now, let's assume the width of the room is "x" decimeters. According to the given information, the length is 30 decimeters more than the width. Therefore, we can write the equation:

Length = Width + 30

67 = x + 30

To find the width, we can subtract 30 from both sides of the equation:

x = 67 - 30

x = 37

So, the width of the room is 37 decimeters.

To calculate the area of the room, we multiply the length and width:

Area = Length * Width

Area = 67 decimeters * 37 decimeters

Area = 2479 square decimeters

Therefore, the area of the room is 2479 square decimeters.
