the perimeter of a triangle is 62, the 1st side is twice the length of the second side, the third side is 6 more than the second side. what is the length of each side?

Respuesta :

We have three sides in this triangle,
first side=2x
second side=x
third side=x+6

Perimeter of a triangle=sum of all sides.
Then, we can suggest this equation:
(2x)+x+(x+6)=62
4x+6=62
4x=62-6
4x=56
x=56/4
x=14

first side=2x=2(14)=28 cm
second side=14 cm
third side=x+6=14+6=20 cm

The length of the sides would be: 28 cm, 14 cm and 20 cm.
