Answer 1

254:2=127
127-73=54
73*54=3942

Answer 2

1)254:2=127(см)-обе стророны 2)127-73=54(см)-2 сторона 3)S=(a*b)=73*54=3942см² Ответ:S=3942см²

Answer 3

Calculation of Rectangle Area and Perimeter

To find the area of a rectangle, we need the length and width of the rectangle. In this case, we are given the perimeter and one side length of the rectangle. We can use this information to calculate the missing side length and then find the area.

Given: - Perimeter of the rectangle: 254 cm - One side length of the rectangle: 73 cm

Finding the Missing Side Length

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we are given the perimeter and one side length. To find the missing side length, we can subtract the given side length from the perimeter and divide the result by 2, since the other side length will be the same.

Let's calculate the missing side length: - Perimeter = 2 * (Length + Width) - 254 cm = 2 * (Length + 73 cm) - 254 cm = 2 * Length + 146 cm - 2 * Length = 254 cm - 146 cm - 2 * Length = 108 cm - Length = 108 cm / 2 - Length = 54 cm

So, the missing side length of the rectangle is 54 cm.

Calculating the Area of the Rectangle

The area of a rectangle is calculated by multiplying the length and width of the rectangle. Now that we have both side lengths, we can calculate the area.

Let's calculate the area: - Area = Length * Width - Area = 54 cm * 73 cm - Area = 3942 cm^2

Therefore, the area of the rectangle is 3942 square centimeters.
