Question

Длина одной стороны прямоугольника равна 2 см., что составляет одну третью часть длины другой стороны.Вычисли периметр и площадь этого прямоугольника. Только не уравнением. спасибо.

Answer 1

2*3=6 (см) длинавторой стороны
(2+6)×2=16 (см) периметр
2×6=12(см) площядь
ответ у 16 см,12см.

Answer 2

2×3=6 см длина другой стороны .... P=2+2+6+6=16 см (или (2+6)×2=16) ... S=2×6=12 см

Answer 3

Calculating the Perimeter and Area of a Rectangle

To calculate the perimeter and area of a rectangle when one side is 2 cm and is one-third the length of the other side, we can use the following steps:

1. Calculate the Length of the Other Side: - Let's denote the length of the other side as x. - Given that one side is 2 cm and is one-third the length of the other side, we can express this as: 2 = (1/3)x. - Solving for x, we get: x = 6 cm.

2. Calculate the Perimeter: - The perimeter of a rectangle is given by the formula: P = 2(l + w), where l is the length and w is the width. - Substituting the values, we get: P = 2(2 + 6) = 2(8) = 16 cm.

3. Calculate the Area: - The area of a rectangle is given by the formula: A = l * w, where l is the length and w is the width. - Substituting the values, we get: A = 2 * 6 = 12 cm^2.

Therefore, the perimeter of the rectangle is 16 cm and the area is 12 cm^2. These calculations are based on the given dimensions and the formulas for perimeter and area of a rectangle.
