Question

the three sides of a triangle are three consecutive numbers such as the perimeter is 63 now tell the three sides length​

Answer 1

Let one side be x

So the other 2 side = (x+1),(x+2)

Perimeter = sum of side = 63

So,

x + (x+1)+(x+2)=63

3x +3 =63

3x = 60

x = 20

So the sides are

20cm,21cm,22cm
