The dimensions of a TV screen are 40" wide and 30" tall. A similar TV has a screen witth of ed. What is the perimeter of the screen of the larger TV?

1 answer

Since the larger TV screen has a width that is 1.2 times wider than the first TV screen, its width would be:

40" x 1.2 = 48"

Since the larger TV screen has a height that is 1.2 times taller than the first TV screen, its height would be:

30" x 1.2 = 36"

To find the perimeter of the larger TV screen, we add all four sides:

Perimeter = 48" + 48" + 36" + 36"

Perimeter = 168"

Therefore, the perimeter of the screen of the larger TV is 168 inches.
