collinear points are points in the same line, like
●-----------------●------------------------------------------●
and the line will always be contained by a plane, so since the line is in a plane, all points in it will also be in the same plane, and therefore be coplanar.

Answer:
47.71
Step-by-step explanation:
Two "special" triangles are involved.
ΔSWR is a 30°-60°-90° right triangle, so will have sides in the ratio 1 : √3 : 2.
ΔUVW is a 45°-45°-90° right triangle so will have sides in the ratio 1 : 1 : √2.
For ΔSWR, the side SW is given as 6, so the other sides are ...
WR = 6√3
RS = 2(6) = 12
For ΔUVW, the side WU is given as 8, so the other sides are ...
UV = VW = 8/√2 = 4√2
Then the perimeter of the figure is ...
P = RS +ST +TU +UV +VW +WR
P = 12 +8 +6 +4√2 +4√2 +6√3 ≈ 47.71
It is 130 so just keep trying to get it.
