The length PQ of the given parallelogram PSQR is determined as 9 cm.
What is the relationship between opposite sides of parallelogram?
Opposite sides of a parallelogram are parallel (congruent).
PQ = RS
2x+5 = 4x+1
2x-4x = 1-5
-2x = -4
x = -4/-2
x = 2
Calculate the length PQ
PQ = 2x+5
PQ = 2(2)+5
PQ = 4+5
PQ = 9cm
