The perimeter of a triangle is the sum of its 3 sides.
Find the perimeter of a right triangle with legs measuring 3 and 4
a + b + c
the formula is 1side multiply by 3
The formula for measuring the area of a square is s2, where s is the length of one of the sides. The perimeter would be 4s.
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
Add the lengths of each side together to get the perimeter.
Lengths of: equal side+equal side+base = perimeter
It depends on what the formula is for: the area or perimeter or some other characteristic.
