Question

Can someone explain please.

Answer 1

Answer:

31.1

Step-by-step explanation:

This is a square of side 22.

The diagonal is 22×sqrt(2)=22×1.4142=31.11

Rounded: 31.1

Answer 2

I believe the answer is 31.1 since, it’s a square it’s equal on all sides, so you used the Pythagorean theorem to final the missing diagonal side, so 22^2 plus 22^2 = c^2
That would give you 968 =c^2, square both sides, you’ll get 31.1
