  1. Step-by-step explanation:

    a

    [tex] = (a = 2x )+ (b = 3x )+(c = 4x) (p = 900cm)[/tex]

    [tex]p = ab + bc + ca [/tex]

    [tex]900 + 2 + 3 + 4[/tex]

    [tex]900 = 9x \div 900[/tex]

    [tex]x = 900 \div 9[/tex]

    [tex]x = 100[/tex]

    [tex]ab = a = 2x = 2 \times 100[/tex]

    therefore

    [tex]a = 200cm[/tex]

    [tex]bc = b = 3x = 3 \times 100[/tex]

    [tex]therefore a = 300cm[/tex]

    [tex]ca = c = 4x = 4 \times 100[/tex]

    [tex]therefore = c = 400cm[/tex]

    s(s-a)( s-b)(s-c)

    450(450200) (450300)(450400)

    450*225*75*150

    5*3*2*5*3*5*3*5*

    33750cm

  2. Step-by-step explanation:

    Let the common multiple be x

    3x+5x+4x=900

    12x=900

    x=75

    3x=75*3=225

    5x=75*5=375

    4x=75*4=300

    Area,

    S=225+375+300/2

    =450

    Area=√450(450-225)(450-375)(450-300)

    =√450*225*75*150

    =5*3*2*5*3*5*3*5

    =33750cm
