To find the perimeter of a triangle, you need to add up the lengths of all its sides. In this particular triangle, we are given:
- Two equal sides measuring 13 centimeters each.
- A third side measuring 4 centimeters.
Let's list out the given sides:
- Side 1 = 13 cm
- Side 2 = 13 cm
- Side 3 = 4 cm
The perimeter [tex]\( P \)[/tex] of a triangle is found by summing the lengths of its three sides:
[tex]\[ P = \text{Side 1} + \text{Side 2} + \text{Side 3} \][/tex]
Substitute the given side lengths into the formula:
[tex]\[ P = 13 \, \text{cm} + 13 \, \text{cm} + 4 \, \text{cm} \][/tex]
Now, perform the addition:
[tex]\[ P = 13 + 13 + 4 \][/tex]
[tex]\[ P = 26 + 4 \][/tex]
[tex]\[ P = 30 \][/tex]
Thus, the perimeter of the triangle is 30 centimeters.
