Answer:
Step-by-step explanation:
Notice that KL = LM and PQ = QR since OL and OQ are perpendicular to both KM and PR.
It follows that QR = (1/2) PR = 20 cm. We also know that MR = 21.
Now in order to solve the problem we just need OQ=OL

Therefore the perimeter of the pentagon is

Add anything that adds up to 3/2
9 x 1/6
<span>(2+6t)(2+6t)(2+6t)(2+6t)(2+6t)(2)=</span><span>15556T^5
</span><span>(2+4t)(2+4t)(2+4t)(2+4t)(2+4t)(2)=</span>2052t^5
