Question

Can anyone help me with this and can you also explain how you got that answer please

Answer 1

Answer:

7.2

Step-by-step explanation:

Use the distance formula:

d = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

Points of the diagonal: (-2, -2) and (2, 4)

d = $\sqrt{(2-(-2))^2+(4-(-2))^2}$

d = $\sqrt{(2+2)^2+(4+2)^2}$

d = $\sqrt{(4)^2+(6)^2}$

d = $\sqrt{16 + 36}$

d = $\sqrt{52}$

d ≈ 7.2
