<span>Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x 
6x = 66
x = 11 
</span><span>Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x 
6x = 66
x = 11</span>

Look at the figure find the value of x for which l || m
Orlov [11]

Answer:

x=5

Step-by-step explanation:


19x and its vertical angle are equal.  Lets call that angle y

<y and 17x are same side interior angles.  Same side interior angles add to 180 if the lines are parallel.  Since l is parallel to m.

<y + 17x=180

We know that y and 19x are equal since they are vertical angles, so we can substitute this in.

19x+ 17x = 180

Combine like terms.

36x = 180

Divide each side by 36

36x/36 = 180/36

x = 5
