Hey there!
Perimeter is the combination of all the sides.
side+side+side+side= P
We know that P, or perimeter, is 14 yards.
And we know that one side is 4 yards.
4 * 2= 8 (we know two sides have to be the same)
14-8= 6
Now we have 6 yards left and two sides. So, we should divide by two.
6/2=3
x=3
I hope this helps!

Answer:
w=3
Step-by-step explanation:
Though I think there is a typo of using <em>x</em> instead of <em>w</em>, this is a matter of simple order of operations
Perimeter is the total value of all sides and because the shape is a rectangle, the other two sides are the same value as the first two.
The perimeter is ---
P = w+4+w+4
We also know that ---
P = 14
So we also now form an equation and use the ladder method:
w+4+w+4 =14 —>
2w+8 = 14 —>
–8 = –8
2w = 6 —>
÷2 = ÷2
w = 3,
or in the case of the typo, x=3.
The missing area for both sides is 48ft²
the missing dimension is 12ft
Add all the areas up
12+36+12+36=96
192-96=96
96÷2=48
48÷4=12
