Answer:
x =31
Step-by-step explanation:
If you see that's a straight line, and the straight line is always 180 degrees, there fore if you use this 56+4x=180 the x will be 31.
x = 31
angles formed on a straight line have a sum of 180°
Thus, 4x + 56 = 180
4x + 56 = 180
* subtract 56 from each side *
56 - 56 cancels out
180 - 56 = 124
4x = 124
* divide both sides by 4 *
4x / 4 = x
124 / 4 = 31
we're left with x = 31
36/3=12x4=48
This is correct all you do is add them up like this:

55.112
(4.5feet)(5.75feet) and that would equal 12.9375 feet²
