Answer:

x²/121 + y²/21 = 1

Step-by-step explanation:

x²/a² + y²/b² = 1

a = 11

c² = a² - b²

b² = a² - c²

b² = 11² - 10²

b² = 21

x²/11² + y²/21 = 1

x²/121 + y²/21 = 1

Answer:

Sorry, it's actually the third one, 4.8 feet

Step-by-step explanation:

First, you divide the length of the family room tv by the length of the tv in Louise's room

5 divided by 1.5 equals 3.33

Then, you divide the width of the family room tv to get the width of Louise's tv

3 divided by 3.33 is 0.9

Now, you follow the formula for perimeter.

(0.9 + 1.5) x 2 = 4.8

The perimeter of Louise's tv is 4.8 feet.
