  • x + 2x + 2 + 2x + 3 = 30
    5x + 5 = 30
    5x = 25
    x = 5

    Sisi terpanjang = 2x + 3 = 2 x 5 + 3 = 13 cm

  • a = x
    b = 2x + 2
    c = 2x + 3
    Keliling = 30 cm

    a + b + c = K
    X + (2x + 2) + (2x + 3) = 30 cm
    5x + 5 = 30
    5x = 25
    X = 5

    a = 5
    b = 12
    c = 13
