Answer:
9 cm
Step-by-step explanation:
In a parallelogram, opposite sides are equal.
RS = PQ
4x + 1 = 2x + 5
Now, to find the value of x,
Step1. Subtract 1 from both sides
4x = 2x + 5 - 1
4x = 2x + 4
Step 2: Subtract 2x from both sides
4x - 2x = 4
2x = 4
Step 3: Divide both sides by 2
x = 4/2
x = 2
PQ = 2x + 5
= 2*2 + 5
= 4 + 5
PQ = 9 cm
