@Michele_Laino ???

Answer 11

hint:
the length of CD, is:
\(x_D-x_c=2-(-4)=2+4=...?\)

Answer 12

\[\Large {x_D} - {x_C} = 2 - \left( 4 \right) = 2 + 4 = ...?\]

Answer 13

6

Answer 14

ok! Sorry I have made a typo:
\[\Large {x_D} - {x_C} = 2 - \left( { - 4} \right) = 2 + 4 = 6\]

Answer 15

so, the height of such rectangle has to be of \(36/6=6 \) units

Answer 16

for example, if I consider the point \(A=(2,2)\) then the length of the segment \(AD\), is:
\[\Large AD = {y_A} - {y_D} = 2 - \left( { - 4} \right) = 2 + 4 = ...?\]

Answer 17

okay so B should be at( -4,2)?

Answer 18

yes!
