| **The perimeter of a triangle is 97 cm one side a cm the second b cm compose an expression to find the 3 sides of a triangle calculate the length of 3 sides if a = 32 cm b = 28 cm**

The perimeter of a triangle is equal to the sum of the length of its three sides and is determined by the formula p = a + b + c, where a is one side of the triangle, b is the second side of the triangle, c is the third side of the triangle.

1). Let’s compose an expression to find the third side of the triangle.

c = p – (a + b);

2). Let’s calculate what the length of the third side of the triangle is equal to.

97 – (32 + 28) = 97 – 60 = 37 centimeters.

Answer: The third side of the triangle is 37 centimeters.
