Answer:
Length=14
Width=5
Step-by-step explanation:
Perimeter is the distance around the object. In this case it's 38. Pretend you're walking along the lines. You will add up all the sides as you walk along them.
(x+6)+(x-3)+(x+6)+(x-3)=38
4x+6=38
4x=32
x=8
Now that you have x, plug it in to the sides to get the answers
Length = x+6 = 8+6=14
Width= x-3 = 8-3 = 5
