Answer 2

\(l^2 = 120\)

\(l = \sqrt{120} \)

You need to simplify \(\sqrt{120}\)

Answer 3

area of the square=a^2 a=the lenght of each side

Answer 4

10.95 ?

Answer 5

a=

\[\sqrt{120}\]

Answer 6

No. You just took the square root using a calculator.
That gives you an approximate value.
The problem wants a simplified exact value.

Answer 7

ohh ok i got D

Answer 8

To simplify the square root of 120, you need to find the largest perfect square factor of the 120.

Answer 9

You should get \[2\sqrt{30}\]

Answer 10

The largest perfect square factor of 120 is 4.

This is how we simplify the root of 120:

\(\sqrt{120} = \sqrt{4 \times 30} = \sqrt 4 \times \sqrt{30} = 2 \times \sqrt{30} = 2 \sqrt{30}\)
