Apothem is the height of a triangel formed by two consecutive vertices with the center. the are of this triangle = 1/2 s 8 = 4s
there area 12 such triangles in the regular 12 side polygon
So area = 12 * 4 s = 48 s
B. It’s bases are congruent
Explanation: A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.

Answer:
Step-by-step explanation:
Let the number of notes is x.
<u>20% of notes is: </u>
<u>40% of the remainder is: </u>
- 40% of 0.8x, so it is
- 0.8x*0.4 =
- 0.32x
<u>Remaining notes are:</u>
<u>Total of the notes:</u>
- 0.2x*10 + 0.32x*5 + 0.48x*2 = 1026
- 2x + 1.6x + 0.96x = 1026
- 4.56x = 1026
- x = 1026/4.56
- x = 225
