Let square side be s. Two semicircles have total area 2 x (1/2) x π(s/2)² = (1/4)πs², identical to the quarter circle’s area (1/4)πs². Subtracting their common overlapping region proves Area(A) = Area(B).

Trisection points divide the base into three equal segments, and both triangles share the same vertex altitude. Area equals (1/2) x base x height, so their areas are identical. Straight dissection along altitudes enables rearrangement.
Four top rectangles match five bottom ones in length, giving 4l = 5b, so l = 5b/4. Area 9lb = 72 yields lb = 8. Solving gives b = 2.53 cm, l = 3.16 cm, and perimeter ≈ 11.38 cm.
Without adherence to laws and civic responsibilities, democratic systems collapse into anarchy, social disorder and mutual distrust. For instance, ignoring traffic laws or tax duties halts public services, disrupts peace and destroys community safety.
After a decision is reached, elected representatives must faithfully implement the agreed choice, respect majority outcomes, maintain complete transparency, work cooperatively with all members and remain accountable to the community they officially represent.
