Пошаговое объяснение:

1)96см+8,4дм=96см+84см=180(см)полупериметр в см

2)180см=1800мм

Ответ:Полупериметр телевизора равен 1800 мм

Answer 2

Calculation of the Semiperimeter of the TV Screen

To find the value of the semiperimeter of the TV screen in millimeters, we need to convert the given dimensions from centimeters and decimeters to millimeters.

Given: - Length of the TV screen = 96 cm - Height of the TV screen = 8.4 dm

To convert centimeters to millimeters, we multiply by 10: - Length of the TV screen in millimeters = 96 cm * 10 mm/cm = 960 mm

To convert decimeters to millimeters, we multiply by 100: - Height of the TV screen in millimeters = 8.4 dm * 100 mm/dm = 840 mm

Now, we can calculate the semiperimeter of the TV screen by adding the length and
