  • Diketahui;
    AB = 4+4+10 = 18cm
    DC = 10
    tinggi = 8

    L. Trapezium = 18+10/2 x 8 = 28/2 x 8
    = 14 x 8 = 112 cm²

    #Make it Simple ^_^

  • DC = 10 cm
    AB = 4 + 4 + 10 = 18 cm

    L = 1/2 x (a + b) x t
    L = 1/2 x (10 + 18) x 8
    L = 28 x 4
    L = 112
    Jadi, jwabannya d
