Question

Two sides of a triangle are 10 cm and 6 cm.Perimeter of triangle is 25 cm,Find the length of third side?

Answer 1

Answer:

9 cm

Step-by-step explanation:

Perimeter of triangle = a+b+c

let, a = 10

     b = 6

     c = c

Perimeter = 25

a+b+c = 25

10+6+c = 25

16+c = 25

c = 25-16

c = 9
