Question

two side of a triangle are the 14 cm and 20 cm the perimeter of the triangle is 48 cm what is the measure of this third side​

Answer 1

Step-by-step explanation:

Let, the length of third side be x

Now,

$perimeter \: of \: triangle = 48cm \: \: \: \: \: \: \: \: \: (given) \\ = > 14cm + 20cm + x = 48cm \\ = > 34cm + x = 48cm \\ = > x = 48cm - 34cm \\ = > x = 14cm$

Therefore,

Length of third side=

$x \\ = 14cm$
