Question

В прямоугольнике длина которого 8см и ширина 6см проведена диагональ.найди площадь треугольника найди периметр прямоугольника.Помогите!!!

Answer 1

1). 8*6=48 (см/кВ) площадь прямоугольника; 2). Проводим диагональ, получаются 2 равных треугольника. 3). 48:2=24 (см/кв) площадь и первого и второго треугольников; 4). (8+6)*2=28 (см) периметр прямоугольника.

Answer 2

Calculation of Triangle Area

To find the area of the triangle formed by the diagonal in the rectangle, we can use the formula for the area of a triangle: Area = (base * height) / 2.

In this case, the base of the triangle is the length of the rectangle, which is 8 cm, and the height is half the width of the rectangle, which is 6 cm. Plugging these values into the formula, we get:

Area = (8 * 6) / 2 = 48 / 2 = 24 square cm.

Therefore, the area of the triangle is 24 square cm.

Calculation of Rectangle Perimeter

To find the perimeter of the rectangle, we can use the formula: Perimeter = 2 * (length + width).

In this case, the length of the rectangle is 8 cm and the width is 6 cm. Plugging these values into the formula, we get:

Perimeter = 2 * (8 + 6) = 2 * 14 = 28 cm.

Therefore, the perimeter of the rectangle is 28 cm.
