==========================================================
Explanation:
x = unknown width
For this rectangle, there are 2 sides of length x, and 2 sides of length 17.
The perimeter is P = 2x+2*17 = 2x+34
Set this equal to the given perimeter (94) and solve for x.
2x+34 = 94
2x = 94-34
2x = 60
x = 60/2
x = 30
The TV is 30 inches wide
