ok i have 2 problems and id appreciate it if someone can help :)
1. given hexagon ABCDEF with diagonal AC being 2 calculate the area and perimeter of the hexagon.

2. the perimeter of an equilateral triangle is equal to its area. find the side length

  1. Anonymous

    Draw line BF, perpendicular to AC
    /_GAC = 30º and /_ABG = 30º
    AG = GC = 1
    AB=1/cos30º=2/sqrt3 BC = CD = DE = EF = FA
    BG = ABsin30º = 1/sqrt3
    Perimeter P = 6AB
    Area = (2)/sqrt3 + 2(2)/sqrt3
