Answer
$P = 94$ cm
Work Step by Step
In a parallelogram, opposite sides are congruent. If $PQ = 35$ cm, then its opposite side is also $35$ cm; also, if $QR = 12$ cm, then its opposite side is also $12$ cm.
We can set up the equation to find the perimeter:
$P = 2l + 2w$
Let's plug in what is known:
$P = 2(35) + 2(12)$
Multiply first, according to order of operations:
$P = 70 + 24$
Add to solve:
$P = 94$ cm
This corresponds to option $C$.
