The perimeter of a triangle is 44 cm. One of its sides is 4 cm smaller than the other and twice as long as the third side. Find the sides of the triangle.

Perimeter of a triangle=sum of all sides.

We have three sides in a triangle;

The third side is : x

The second side is:2x

The first side is : 2x+4

Then we have the following equation.

x+2x + (2x+4) = 44

5x=40

x=40/5

x=7

The third side is x=8

The second side is 2x=2*8=16

The first side is: 2x+4=2*8+4=20

The sides of the triangle would be: 8 cm, 16 cm and 20 cm
