Answer:
Step-by-step explanation:
Let us say that the width is x
So this means that the legth is 3 times the width or 3x
Perimeter means to add up all the sides in the shape
So form an equation : 2(x)+2(3x)=36
And once you solve it you get x=36/8.
The width is 3(36/8) which is 13.5
Hope this Helps
Stay Safe!!
