Answer:
Television screen height = 4 feet
Explanation:
The formula for the perimeter of a rectangle (in terms of height) is given by:
P = 2h + 2w, where:
- P is the perimeter,
- h is the height,
- and w is the width.
Thus, we can determine the height of the screen by substituting 20 for P and 6 for w in the rectangle perimeter formula:
20 = 2h + 2(6)
(20 = 2h + 12) - 12
(8 = 2h) / 2
4 = h
Therefore, the height of the television screen is 4 feet.
