Area of the trapezium = 1/2(18 + 6) x 12
Area of the trapezium = 144 in²
------------------------------------------------
Answer: Area = 144 in²

Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
If the circumference is half of the perimeter than the area for both circles would be half of them find one circles area and half it
The answer is (4x20) + (4x4) which equals 96
Answer: 0.8
