Question

Реши задачу. Часть прямоугольной площадки длиной 17 м и шириной 12 м заняли цветником прямоугольной формы. Длина цветника 14 м, а ширина 9 м. Определи площадь, не занятую цветником.

Answer 1

1) 17* 12 =204 м2 - площадь всей площадки
2) 14*9 =126 м2 площадь цветника
3) 204-126 =78 м2 незанятая площадь
Ответ 78м2

Answer 2

17-14=3
12-9=3
разделим остаток уч. на 2 части 
стороны одного уч. равны 3 и 9, стороны 2 уч. равны 17 и 3
вычитаем S этих уч. =27 и 51, и сложим = 78

Answer 3

Problem Analysis

We are given a rectangular platform with dimensions 17m by 12m. A rectangular flowerbed is placed on the platform, with dimensions 14m by 9m. We need to determine the area of the platform that is not occupied by the flowerbed.

Solution

To find the area not occupied by the flowerbed, we need to subtract the area of the flowerbed from the total area of the platform.

The total area of the platform is given by the formula: length x width.

The area of the flowerbed is given by the formula: length x width.

To find the area not occupied by the flowerbed, we subtract the area of the flowerbed from the total area of the platform.

Let's calculate the area not occupied by the flowerbed:

Total area of the platform = 17m x 12m = 204m².

Area of the flowerbed = 14m x 9m = 126m².

Area not occupied by the flowerbed = Total area of the platform - Area of the flowerbed = 204m² - 126m² = 78m².

Therefore, the area not occupied by the flowerbed is 78m².

Answer

The area not occupied by the flowerbed is 78m².
