The perimeter of a triangle is equal to the sum of the lengths of its sides.
P = a + b + c, where:
a, b, c – the lengths of the sides of the triangle.
If a = 7 cm, b = 7 cm, c = x cm, then:
P = 7 + 7 + x;
P = (14 + x) cm.
Answer: The perimeter of the triangle in the form of an expression is P = (14 + x) cm.
