The total length of a boundary defines the perimeter of an equilateral triangle.
<h3>What is the Perimeter of an Equilateral Triangle?</h3>
- The total of the three sides makes up the perimeter of an equilateral triangle.
- The following fundamental characteristics define a triangle as being equilateral:
- The three sides are equal.
- There is a 60° angle between all three.
- The sides of the triangle PQ = QR = RP in the following illustration have equal lengths.
- The triangle's angles are also equal in addition to this. An equilateral triangle is what this is.
- An equilateral triangle's perimeter is now equal to 3a, where a denotes one of the triangle's sides.
- Perimeter of Equilateral Triangle Formula : P = 3a, where 'a' stands for one of the triangle's sides, is a simple formula for calculating an equilateral triangle's perimeter. An equilateral triangle has three equal sides, hence the sum is equal to three equal sides, or 3a.
- Additional equilateral triangle formulas include the following: When we need to determine a triangle's height from its sides, we can apply the following formula: Equilateral Triangle Height = (3a)/2
- The semi-perimeter of an equilateral triangle must be determined in a few situations. Half of a perimeter, or semi-perimeter, is equal to 3a/2, which is derived using the formula semi-perimeter = (a + a + a)/2.

Work Shown:
Let x be some integer from the set {..., -3, -2, -1, 0, 1, 2, 3, ...}.
The multiplicative inverse of x is a number y such that x*y = 1.
Since we want x and y to be the same, this means y = x
Use substitution to go from
x*y = 1
to
x*x = 1
Basically I've replaced y with x
Now solve for x
x*x = 1
x^2 = 1
x = +-sqrt(1)
x = 1 or x = -1
There are 2 values of x where they are their own multiplicative inverse
1*1 = 1
(-1)*(-1) = 1
