Question

В углу прямоугольного двора размером 50х30 стоит прямоугольный дом размером 20х10. Подсчитать площадь дома, свободную площадь двора и длину забора. Примечание: в углу, где дом, забора нет. Для программы кумир

Answer 1

(50-20)х(30-10)=30х20

Answer 2

Calculation of House Area, Free Yard Area, and Fence Length

To calculate the area of the house, we can multiply its length by its width. Given that the house has dimensions of 20x10, the area of the house is:

House Area = Length x Width = 20 x 10 = 200 square units.

To calculate the free yard area, we need to subtract the area of the house from the total area of the rectangular yard. The yard has dimensions of 50x30, so its total area is:

Yard Area = Length x Width = 50 x 30 = 1500 square units.

Subtracting the area of the house from the yard area gives us the free yard area:

Free Yard Area = Yard Area - House Area = 1500 - 200 = 1300 square units.

Lastly, to calculate the length of the fence, we need to consider that there is no fence in the corner where the house is located. Therefore, we need to calculate the perimeter of the yard and subtract the length of the house from it. The perimeter of a rectangle is given by the formula:

Perimeter = 2 x (Length + Width).

For the yard, the perimeter is:

Yard Perimeter = 2 x (Length + Width) = 2 x (50 + 30) = 2 x 80 = 160 units.

Subtracting the length of the house from the yard perimeter gives us the length of the fence:

Fence Length = Yard Perimeter - Length of House = 160 - 20 = 140 units.

Therefore, the calculations for the given scenario are as follows: - House Area: 200 square units - Free Yard Area: 1300 square units - Fence Length: 140 units.
