Question

Начертите прямоугольнтк со сторонами 5 см и 3 см.Найдите его площадь и периметр

Answer 1

Р =(а +в) х2
( 5 +3) х2 = 16(см) периметр прямоугольника

S=а х в
5 х 3 = 15 (кв.см) площадь прямоугольника

Answer 2

Чертишь просто и  все чего тут трудного?

Answer 3

Drawing a Rectangle

To draw a rectangle with sides measuring 5 cm and 3 cm, follow these steps:

1. Take a ruler and draw a straight line segment measuring 5 cm. 2. From one end of the line segment, draw another line segment perpendicular to the first one, measuring 3 cm. 3. Connect the endpoints of the two line segments to form a rectangle.

The resulting rectangle will have sides measuring 5 cm and 3 cm.

Calculating the Area

To find the area of the rectangle, multiply the length of one side by the length of the other side. In this case, the length of one side is 5 cm and the length of the other side is 3 cm.

Area = length × width

Area = 5 cm × 3 cm

Area = 15 cm².

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

Calculating the Perimeter

To find the perimeter of the rectangle, add up the lengths of all four sides. In this case, the length of one side is 5 cm and the length of the adjacent side is 3 cm.

Perimeter = 2 × (length + width)

Perimeter = 2 × (5 cm + 3 cm)

Perimeter = 2 × 8 cm

Perimeter = 16 cm.

Therefore, the perimeter of the rectangle is 16 centimeters.
