Answer:
[tex]Length=16\\width=64[/tex]
Step-by-step explanation:
Perimeter of the rectangle= 128
Let, the Length of the rectangle be 'L'
Width=3*L
Perimeter of the rectangle =2(Length+width)
[tex]128=2(L+3L)\\\\128=2(4L)\\\\4L=128/2\\\\4L=64\\\\L=64/4\\\\L=16\\\\length=16[/tex]
Width=4*L= 4*16= 64
[tex]Length=16\\width=64[/tex]
