*The Perimeter of a rectangle is 42 inches. If the length is doubled and the width is tripled, the perimeter becomes 102 inches. Find the length and width of the original rectangle.*
You can put this solution on YOUR website! 42=2L+2W--->2L=42-2W.....eq 1
:
102=2(2L)+3(2W)......eq 2
:
take 2L's value from eq 1 and plug it into eq 2
:
102=2(42-2W)+6W
:
102=84-4W+6W
:
18=2W
:
W=9 in
:
L=(42-2(9))/2=24/2=12 in
