Answer:
Length=12 inches Width=6 inches
Step-by-step explanation:
X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.

X = y + 3
2x + y = 9
Solution..
---------------
Substitute for x=y+3 in the second equation...
2x+y = 9
2(y+3)+y=9
2y+6+y=9
3y+6=9
3y=9-6
3y=3
y=3/3
y=1....
Substitute for y=1 in the first equation...
x=y+3
x = 1+3
x=4..
Am sure the answer is quite evident now...
