PR = 20
Step-by-step explanation:
The perimeter is the sum of the 3 sides, thus
4z + z + 3 + 3z + 2 = 45 ← simplify left side
8z + 5 = 45 ( subtract 5 from both sides )
8z = 40 ( divide both sides by 8 )
z = 5
PR = 4z = 4 × 5 = 20
3 because there are it takes 4 of 1/4 to complete 4/4 and make it one
