The first side of a triangle is 8m shorter than the second side. The third side is 4 times the first side. The perimeter is 26 m. Find the length of each side.

z= second side

z-8 = first side

4 (z-8) = third side

 

z + z -8 + 4 (z-8) = 26

6z - 40=26

6z=66

z=11            second side         z-8 =  3   is first side    third side 4(z-8) = 12
