one side of a triangle is 6 cm
let the third side be x cm
∴the second side is=2x cm
ATP
6 cm+ x cm+2x cm= 18 cm -
x cm+2x cm= 18 cm -6 cm
3x cm= 12cm
x = 12cm ÷3
x = 4cm
the third side be 4 cmANS
the second side is=2x4 cm=8cm ANS

Let the third side of the Δ(triangle) be = x
One side of a triangle = 6cm
The second side = 2xcm
⇒ 6cm + x cm + 2x cm = 18cm
⇒ 6 + 3x = 18cm
⇒ 3x = 18 - 6
⇒ x = 12/3
⇒ x = 4
1st side = 6cm
2nd side = x = 4cm
3rd side = 2 × x = 2 × 4 = 8cm
