Lengths of: equal side+equal side+base = perimeter
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.

Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
Lengths of: equal side+equal side+base = perimeter
Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
Just add each of the three lengths of the triangle together. In an equilateral triangle, all side are the same. In an isosceles, 2 sides are the same and one is different.
Perimeter = 81+81+29 = 191 units of measurement
Perimeter = 45+58+58 = 161 units of measurement
An isosceles triangle has 3 sides 2 of which are equal in length
An isosceles triangle is a triangle with two equal sides. To find the perimeter of the triangle, you simply need to add together the lengths of the base and the two sides. So: 3.9 + 4.6 +4.6 = 13.1 inches.
13 cm and it is an isosceles triangle 55 - 2*21 = 13
If it is an isosceles triangle then side BC is 15cm and side AC is 15m
You could have an isosceles triangle with sides 3, 3, and 2. I think that's the only one.
