Add all three sides. Perimeter = 15 + 17 + 10 = 42
Perimeter of a triangle is given by: sum of the three sides =(10+15+18)cm =43cm Done.
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter of the triangle with sides measuring 3 inches, 5 inches, and 7 inches is 3 + 5 + 7 = 15 inches.
Perimeter: 15+20+25 = 60 units
The perimeter is the sum of all sides. An equilateral triangle has three sides of equal length. So if one side is 5 inches, and we have three of these, we get a perimeter of 15 inches.
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45

The perimeter of any triangle is the sum of its 3 sides
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter of the triangle with sides measuring 3 inches, 5 inches, and 7 inches is 3 + 5 + 7 = 15 inches.
42cm
Perimeter: 15+20+25 = 60 units
The perimeter is the sum of all sides. An equilateral triangle has three sides of equal length. So if one side is 5 inches, and we have three of these, we get a perimeter of 15 inches.
Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified. Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
Yes 5+5+5 = 15 6+6+3 = 15
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
50
15 cm * 6 sides = 90 cm perimeter
