Question

Ширина прямоугольника равна 60 см а длина в 2 раза больше вычислите площадь и периметр прямоугольника

Answer 1

Ответ:

S = 7200 $cm^{2}$

P = 360 $cm$

Пошаговое объяснение:

1) Найдем длину

60*2=120 (см)

2) Площадь прямоугольника равна S=ab

S = 60*120 = 7200 ($cm^{2}$)

3) Теперь найдем периметр прямоугольника. Он вычисляется по формуле P=2(a+b)

P = 2*(120+60) = 360 (см)

Answer 2

Calculation of the Area and Perimeter of a Rectangle

To calculate the area and perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, the width of the rectangle is given as 60 cm, and the length is twice the width.

Let's calculate the area and perimeter step by step:

1. Calculate the length of the rectangle: - The length is given as twice the width. - Therefore, the length = 2 * 60 cm = 120 cm.

2. Calculate the area of the rectangle: - The area of a rectangle is given by the formula: Area = length * width. - Substituting the values, we get: Area = 120 cm * 60 cm = 7200 cm².

3. Calculate the perimeter of the rectangle: - The perimeter of a rectangle is given by the formula: Perimeter = 2 * (length + width). - Substituting the values, we get: Perimeter = 2 * (120 cm + 60 cm) = 2 * 180 cm = 360 cm.

Therefore, the area of the rectangle is 7200 cm² and the perimeter is 360 cm.

Please note that the above calculations are based on the given information and assumptions. If there are any additional specifications or constraints, please let me know.
