A rectangular room is 5m longer than it is wide, and its perimeter is
P=22m.
Find the dimension of the room.
L=W%2B5m......eq.1
P=2%28L%2BW%29....substitute L from eq.1 and P
22m=2%28W%2B5m%2BW%29...............solve for W
22m%2F2=W%2B5m%2BW
11m-5m=2W
6m=2W
W=6m%2F2
W=3m

go to L=W%2B5m......eq.1, plug in W
L=3m%2B5m
L=8m

so,the dimension of the room are +8m by 3m
