Question

Вычислите площадь и периметр прямоугольника если одна сторона его 1,9м а другая в 4 раза длиннее. Кто быстрее за 10 мин до выхода задание тот получит бонус +5б

Answer 1

1)1.9 ×4=7.6-вторая сторона 2)S=1.9×7.6=14.44 3)P=1.9×2+7.6×2=19

Answer 2

Calculation of the Rectangle's Area and Perimeter

To calculate the area and perimeter of a rectangle, we need to know the lengths of its sides. In this case, one side of the rectangle is given as 1.9 meters, and the other side is 4 times longer than the first side.

Let's calculate the length of the second side: - The first side is 1.9 meters. - The second side is 4 times longer than the first side, so it would be 1.9 * 4 = 7.6 meters.

Now that we have the lengths of both sides, we can calculate the area and perimeter of the rectangle.

Area of the Rectangle: The area of a rectangle is calculated by multiplying the length of one side by the length of the other side. In this case, the lengths are 1.9 meters and 7.6 meters.

Area = length * width = 1.9 meters * 7.6 meters = 14.44 square meters.

Perimeter of the Rectangle: The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, we have two sides with lengths 1.9 meters and 7.6 meters.

Perimeter = 2 * (length + width) = 2 * (1.9 meters + 7.6 meters) = 2 * 9.5 meters = 19 meters.

Therefore, the area of the rectangle is 14.44 square meters, and the perimeter is 19 meters.
