Question

Периметр прямоугольника равен 54см, длина – 14см. Найти площадь прямоугольника.​

Answer 1

1) 54 - 14 • 2 = 26 (см) - 2 ширины
2) 26 : 2 = 13 (см) - ширина
3) S = 26 • 13
S = 338 см2
Ответ S = 338 см2

Answer 2

Ответ:

182 см²

Пошаговое объяснение:

54:2-14=27-14=13 (см) - ширина прямоугольника;

13*14=182 (см²) - площадь прямоугольника.

Answer 3

Finding the Area of a Rectangle

To find the area of a rectangle, we need to know the length and width of the rectangle. In this case, we are given the perimeter of the rectangle, which is 54 cm, and the length, which is 14 cm. We can use this information to find the width and then calculate the area.

Calculating the Width

The perimeter of a rectangle is given by the formula: perimeter = 2 * (length + width). We can rearrange this formula to solve for the width: width = (perimeter - 2 * length) / 2.

Substituting the given values, we have: width = (54 - 2 * 14) / 2 = 26 / 2 = 13 cm.

Calculating the Area

The area of a rectangle is given by the formula: area = length * width. Substituting the given values, we have: area = 14 cm * 13 cm = 182 cm^2.

Therefore, the area of the rectangle is 182 square centimeters.
