Question

Вычисли периметр равностороннего треугольника если длина его стороны равна 25 миллиметров Во сколько раз увеличиваются периметр треугольника если длину его стороны увеличить в 3 раза

Answer 1

1)Т.к. он равносторнний, то 25*3=75мм(периметр)
2)25*3=75 - теперь это сторона, увеличенная в три раза
3)75*3=225мм(периметр)

Answer 2

Calculating the Perimeter of an Equilateral Triangle

To calculate the perimeter of an equilateral triangle when the length of its side is 25 millimeters, we can use the formula: Perimeter = 3 * side length

Substituting the given side length of 25 millimeters into the formula: Perimeter = 3 * 25 mm = 75 mm

Therefore, the perimeter of the equilateral triangle with a side length of 25 millimeters is 75 millimeters.

Increasing the Side Length by 3 Times

If we increase the length of the side of the equilateral triangle by 3 times, we can calculate the new perimeter using the same formula: New Perimeter = 3 * (3 * side length)

Substituting the increased side length of 25 millimeters by 3 times into the formula: New Perimeter = 3 * (3 * 25 mm) = 3 * 75 mm = 225 mm

So, if the length of the side of the equilateral triangle is increased by 3 times, the new perimeter will be 225 millimeters.

Ratio of the New Perimeter to the Original Perimeter

To find out in how many times the perimeter increases when the side length is increased by 3 times, we can calculate the ratio of the new perimeter to the original perimeter: Ratio = New Perimeter / Original Perimeter

Substituting the values: Ratio = 225 mm / 75 mm = 3

Therefore, when the length of the side of the equilateral triangle is increased by 3 times, the perimeter increases in 3 times.
