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
