Answer 2

Answer:

length of one side of triangle=13cm

length of second side of triangle=18cm

perimeter of triangle =48cm

let the third side be x

as we know that perimeter of triangle is sum of all sides so,

13cm+18cm+x=48cm

31cm+x=48cm

x=48cm- 31cm

x=17cm

therefore the third side of triangle will be 17cm
