Answer 1

Pквадр=4*6.7=26.8
Pтреуг=3*7.6=22.8
У квадрта больше

Answer 2

Perimeter of a Square

To find the perimeter of a square, you need to know the length of one side. In this case, the length of one side of the square is given as 6 cm 7 mm.

The perimeter of a square is calculated by multiplying the length of one side by 4, since all sides of a square are equal in length.

Therefore, the perimeter of the square with a side length of 6 cm 7 mm is:

Perimeter = 4 * (6 cm 7 mm)

To calculate the perimeter, we need to convert the measurements to a consistent unit. Let's convert the millimeters to centimeters:

1 cm = 10 mm

Therefore, 7 mm is equal to 0.7 cm.

Now we can calculate the perimeter:

Perimeter = 4 * (6 cm + 0.7 cm)

Perimeter = 4 * 6.7 cm

Perimeter = 26.8 cm

So, the perimeter of the square is 26.8 cm.

Perimeter of an Equilateral Triangle

To find the perimeter of an equilateral triangle, you need to know the length of one side. In this case, the length of one side of the equilateral triangle is given as 7 cm 6 mm.

The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, since all sides of an equilateral triangle are equal in length.

Therefore, the perimeter of the equilateral triangle with a side length of 7 cm 6 mm is:

Perimeter = 3 * (7 cm 6 mm)

Again, let's convert the millimeters to centimeters:

1 cm = 10 mm

Therefore, 6 mm is equal to 0.6 cm.

Now we can calculate the perimeter:

Perimeter = 3 * (7 cm + 0.6 cm)

Perimeter = 3 * 7.6 cm

Perimeter = 22.8 cm

So, the perimeter of the equilateral triangle is 22.8 cm.

Comparison of Perimeters

To compare the perimeters of the square and the equilateral triangle, we can subtract the perimeter of the square from the perimeter of the equilateral triangle:

Perimeter difference = Perimeter of equilateral triangle - Perimeter of square

Perimeter difference = 22.8 cm - 26.8 cm

Perimeter difference = -4 cm

The negative value indicates that the perimeter of the square is greater than the perimeter of the equilateral triangle. The difference in perimeters is 4 cm.

Therefore, the square has a greater perimeter than the equilateral triangle by 4 cm.
