Question

периметр и площядь прямоугольника длинна 14 см ширина в 2 раза меньше

Answer 1

1)14:2=7 см ширина

2)14 * 7=98 площадь

3)(14+7) * 2=42 см периметр

Ответ:площадь-98см

Периметр-42см

Answer 2

Длина 14 см

Ширина 7 см

Периметр = 2*14 + 2*7 = 28 + 14 = 42 (см)

Площадь = 14 * 7 = 98 (см^2)

Answer 3

Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know the length and width of the rectangle. In this case, the length of the rectangle is 14 cm and the width is 2 times smaller than the length.

Perimeter of a Rectangle

The perimeter of a rectangle is the sum of all its sides. For a rectangle with length (L) and width (W), the perimeter (P) can be calculated using the formula: P = 2(L + W).

In this case, the length (L) is 14 cm and the width (W) is 2 times smaller than the length. Therefore, the width (W) is 14 cm / 2 = 7 cm.

Using the formula, we can calculate the perimeter (P): P = 2(14 cm + 7 cm) = 2(21 cm) = 42 cm.

So, the perimeter of the rectangle is 42 cm.

Area of a Rectangle

The area of a rectangle is the product of its length and width. For a rectangle with length (L) and width (W), the area (A) can be calculated using the formula: A = L * W.

In this case, the length (L) is 14 cm and the width (W) is 7 cm.

Using the formula, we can calculate the area (A): A = 14 cm * 7 cm = 98 cm^2.

So, the area of the rectangle is 98 cm^2.

Therefore, the perimeter of the rectangle is 42 cm and the area is 98 cm^2.
