Finding the Third Side of a Triangle

To find the length of the third side of a triangle, we can use the fact that the perimeter of the triangle is given as 9.36 cm. We are also given that one side of the triangle is 3.05 cm long, and the second side is 1.98 cm longer than the first side.

Let's denote the length of the first side as x cm. Since the second side is 1.98 cm longer than the first side, the length of the second side can be expressed as x + 1.98 cm.

To find the length of the third side, we can subtract the sum of the lengths of the first two sides from the perimeter of the triangle:

Perimeter = Length of First Side + Length of Second Side + Length of Third Side

Substituting the given values, we have:

9.36 cm = x cm + (x + 1.98) cm + Length of Third Side

Simplifying the equation, we get:

9.36 cm = 2x + 1.98 cm + Length of Third Side

Rearranging the equation, we find:

Length of Third Side = 9.36 cm - 2x - 1.98 cm

Now, we can substitute the value of x to find the length of the third side.

Please note that we do not have the value of x in the given information. If you provide the value of x, I can calculate the length of the third side for you.
