# The perimeter of the triangle below is 41 units. Find the length

The perimeter of the triangle below is 41 units. Find the length of side QR .

2z, 3z-2, z+1

Click on "Explain"
if you need help.
Given perimeter = 41

2z + 3z - 2 + z + 1 = 41

6z - 1 = 41

6z = 42

z = 7

2z = 2*7 = 14
3z - 2 = 3*7 - 2 = 19
z+1 = 7+1 = 8

Three sides will be 14 units, 19 units, 8 units

P/ 3z-2 Q

tried to make a perimeter, lol

From your figure, seems that z+1 is QR.

QR = z+1 = 7+1 = 8 units
