It is 4 + 3 + 2 = 9 inches. Simple!
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.
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
It is: 3*1 = 3 inches
3 + 3 + 5 = 11 inches
It is: 3*9 = 27 inches
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.
You add the lengths of all the sides together. For an example, if the sides of a triangle were: 2 inches, 3 inches, and 5 inches, you would add 2, 3, and 5 together to get 10 inches.
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
6 and 3/8
4 inches x 3 sides = 12 inches for the perimeter.
It is: 3*1 = 3 inches
That would depend on the length of the 3rd side but in general the perimeter of any triangle is the sum of its 3 sides
3 + 3 + 5 = 11 inches
It is: 3*9 = 27 inches
It is: 3*44 = 132 inches
The dimensions of the scalene triangle could be 7 by 5 by 3 inches
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
