If the diagonal of the square is 13 units long, how long is each side of the square to the nearest tenth?

Solution:

Given that,

Diagonal of the square is 13 units long

Let the diagonal be "d" and side of the square be "s"

The diagonal of square is given as:

Where, "s" is the length of any side

Given that,

d = 13 units

Thus the length of each side of square is 9.2 units

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
