Question

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

Answer 1

7.2

Explanation:

Use the distance formula:

d =
`√((x2-x1)^2+(y2-y1)^2)`

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

d =
`√((2-(-2))^2+(4-(-2))^2)`

d =
`√((2+2)^2+(4+2)^2)`

d =
`√((4)^2+(6)^2)`

d =
`√(16 + 36)`

d =
`√(52)`

d ≈ 7.2
