A. 5.4 feet
B. 0.2 feet
C. 6.5 feet
D. 21.7 feet

Answer :

To find the diagonal measurement of the TV in feet, follow these steps:

1. Understand the given measurement: The TV's diagonal is given as 65 inches.

2. Convert inches to feet: Since there are 12 inches in a foot, divide the diagonal measurement in inches by 12 to convert it to feet.

[tex]\[
\text{Diagonal in feet} = \frac{65}{12} = 5.4166667 \ldots
\][/tex]

3. Round to the nearest tenth: To round the result to one decimal place (tenths), look at the digit in the hundredths place. Since it is 1 digit (6), which is 5 or greater, round up.

[tex]\[
\text{Rounded diagonal in feet} = 5.4
\][/tex]

Therefore, the diagonal measurement of the TV is approximately 5.4 feet. The correct option is 5.4 feet.
