Hi,



L + w = 555

(6w+30) + w = 555

    7w = 525

     w = 75m and L = 480m  6%2A75%2B30

+perimeter+=+2%2A%28length+%2B+width%29+
from problem, +length=%286%2Awidth%29+%2B+30%29
--->1110=2%2A%28length+%2B+width%29
--->1110=+2%2A%286+%2A+width%29+%2B+30+%2B+width
--->525=+7+%2A+width
--->width=+75
therefore length=+%286+%2A+75%29+%2B+30+=+480
