    S=pr
    for i=1 to 6
    all triangles have altitude r and side p
    Si=0.5pr=0.5S
    .-.

    CD = CE = AF = AG = BH = BM = s
    (s= 1/2 perimeter)
    S1 = 1/2.r.CD = 1/2.r.s = 1/2 S
    S2 = 1/2.r.CE = 1/2.r.s = 1/2 S
    S3 = 1/2.r.AF = 1/2.r.s = 1/2 S
    S4 = 1/2.r.AG = 1/2.r.s = 1/2 S
    S5 = 1/2.r.BH = 1/2.r.s = 1/2 S
    S6 = 1/2.r.BM = 1/2.r.s = 1/2 S
