Question

The sides of a triangle are in form of consecutive even integers. If its perimeter is 48cm, find the measure of all side

Answer 1

let first side be x so next sides will be x+1 and x+2

equation will be x+x+2+x+4=48

3x=42

x=14

sides will be 14, 16 and 18

mark me as brainliest

Answer 2

Let one side be x cm

Therefore, Other 2 sides will be x+2, x+4

-> x+x+2+x+4 = 48

->3x+6=48

->x=14

therefore x+2 = 16

x+4= 18

hope it helps!!
