Answer:
18 inches, assuming that the height is the length of the TV screen.
Step-by-step explanation:
First off, the shape of a TV screen is a rectangle.
To get the area of a rectangle, the equation would be:
H * W = A
where H = height, W = Width, and A = area.
If we pluck in the values given in the question, we get:
H * 32 = 576
To find out H, we have to get rid of the 32.
To do that, we divide both sides by 32.
Therefore, the equation is now:
H = 18.
Thus, the height of the TV screen is 18 inches.
