Question

The perimeter of a triangle is 34cm. What are the lengths of the sides if the first side is twice the length of the second side and the third side is 2cm longer than the second side?

Answer 1

8sm, 16sm, 10sm

Explanation:

the first side of the triangle: x

the other side of the triangle: 2x

the third side of the triangle: x+2

the perimeter of the triangle: x+2x+x+2=34

4x=32

x=8

2*8=16

8+2=10
