Your question is not clear!

It should be - The side of a triangle are 3.7cm and 4.5cm if it's perimeter is 15 cm find it third side.

$\huge\rightarrow$ Perimeter of trinagle = Sum of 3 sides

$\huge\rightarrow$ 15 = 3.7 + 4.5 + x

$\huge\rightarrow$ 15 = 8.6 + x

$\huge\rightarrow$ x = 6.8

Third side is 6.8 cm.
