if given that the length L of a rectangle is six times its width W, we have
L=6W ....eq.1
If the area of the rectangle is A=150, we have
A=LW=150
LW=150...substitute L with 6W
6W%2AW=150
W%5E2=150%2F6
W%5E2=25
W=sqrt%2825%29
W=+5
and, L=6W =>L=6%2A5 =>L=30
then,
P=2%28L%2BW%29
P=2%2830%2B5%29
P=2%2A35
P=70
