Question

Длина прямоугольника 46 см это больше чем ширина 12 см Найди периметр и площадь прямоугольника

Answer 1

Пошаговое объяснение:

Длина а=46 см

Ширина b=46-12=34 cм

Р=2(а+b)=2(46+34)=2×80=160 cм

S=a×b=46×34=1564 cм^2

Ответ : Р=160 см S=1564 cм^2

Answer 2

Calculating the Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle with a length of 46 cm and a width of 12 cm, we can use the following formulas:

1. Perimeter of a Rectangle: The perimeter (P) of a rectangle is given by the formula: \[ P = 2*(length + width) \]

2. Area of a Rectangle: The area (A) of a rectangle is given by the formula: \[ A = length * width \]

Calculations

Using the given length and width: - Length = 46 cm - Width = 12 cm

We can calculate the perimeter and area using the above formulas.

1. Perimeter: \[ P = 2*(46 + 12) = 2*58 = 116 \]

Therefore, the perimeter of the rectangle is 116 cm.

2. Area: \[ A = 46 * 12 = 552 \]

Therefore, the area of the rectangle is 552 square cm.

So, the perimeter of the rectangle is 116 cm and the area is 552 square cm.
