The perimeter of rectangle ABCD is 256 inches. It's length is 3 times as long as its width. Find the area of triangle ABC.

  • math -

    width --- x
    length --- 3x

    2(x+3x) = 256
    8x = 256
    x = 32

    width = 32
    length = 96
    Area = 32(96) = 3072

    U for got to divide by 1/2 it should be 1,536

  • math -

    P= 2(L+B)
    258= 2( 3x + 1x)
    258= 2 ( 4x )
    258= 8
    43*3
    86cm 258 1/2 6
    43cm
    A= B*H 1/2
    = 43* 86 1/2
    =3698cm 1/2 = 1849 cm2
