Take of 8 meters twice (One from each lenght) and you get 432. Divide by 6 since each length is now twice the width and you get 432/6 = 72
So width is 72 and length is 72 x 2 + 8 = 152
152 x 2 = 304
72 x 2 = 144
304 + 144 =448

I'll help U solve it -- but U have to do your homework!
P=perimeter // W=width // L=length
P=448
L+W+L+W=448, correct?
U know half of P=L+W, 224 (with me so far?)
L=2W+8
solve for L (oh man someone beat me to it!)
by setting what U know into the equation:
2(2W+8)+2W=448
4W+16+2W=448
6W=432
W=72
L=2(72)+8=144+8=152
And there U have it. L=152

P = 2L + 2W
L = 2W + 8
2(2W + 8) + 2W = 448
4W + 16 + 2W = 448
6W = 432
W = 72
L = 2(72) + 8 = 144 + 8 = 152

L + W = 224
(2W + 8) + W = 224
3W = 216
W = 72 m
L = 152 m
