Question

Длина прямоугольника 5см, Ширина прямоугольника 3см, Периметр прямоугольника? Площадь прямоугольника?

Answer 1

Периметр: (5+3)*2=16см,
площадь: 5*3=15см²

Answer 2

Perimeter of the Rectangle

To find the perimeter of a rectangle, you need to add up the lengths of all its sides. In this case, the length of the rectangle is 5 cm and the width is 3 cm. Therefore, the perimeter can be calculated as follows:

Perimeter = 2 * (Length + Width)

Perimeter = 2 * (5 cm + 3 cm) = 2 * 8 cm = 16 cm.

So, the perimeter of the rectangle is 16 cm.

Area of the Rectangle

The area of a rectangle can be calculated by multiplying its length and width. In this case, the length of the rectangle is 5 cm and the width is 3 cm. Therefore, the area can be calculated as follows:

Area = Length * Width

Area = 5 cm * 3 cm = 15 cm^2.

So, the area of the rectangle is 15 square centimeters.
