Question

Периметр прямоугольника 34 см. Одга сторона 8 см. Найдите площадь прямоугольника

Answer 1

Р(периметр):34 см. А(длина):8см S(площадь):?cм² В(ширина):?см 1)В=34:2-8=8(см) 2)S=а*(умножить)*в=8*8=64(см²)

Answer 2

Р = (А + В) х2
( 34-8 х 2) : 2 = 9 (см) вторая сторона

S = A x B
8 х 9 =72(кв. см.) площадь прямоугольника

Answer 3

Calculation of Rectangle's Area

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 34 cm, and one side of the rectangle, which is 8 cm.

To find the missing side and calculate the area, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 * (Length + Width)

Given that the perimeter is 34 cm and one side is 8 cm, we can substitute these values into the formula and solve for the missing side:

34 = 2 * (8 + Width)

Dividing both sides of the equation by 2, we get:

17 = 8 + Width

Subtracting 8 from both sides, we find:

Width = 9 cm

Now that we have both the length and width of the rectangle, we can calculate the area using the formula:

Area = Length * Width

Substituting the values, we get:

Area = 8 cm * 9 cm = 72 cm²

Therefore, the area of the rectangle is 72 cm².
