Answer 1

$\huge{Hey Dude!!!}$

☆☞ Here is ur answer ☜☆

☆☞ It is given that the equation of the line AB is y = 3.
I.e., AB is 3 units far from the x-axis and is above the x-axis.

☆☞ It is also given that the rectangle ABCD is symmetric about the x and the y­­-axis. Hence, the distances of lines AB and CD from the x-axis will be the same.

☆☞So, CD is 3 units far from the x-axis and is below the x-axis; and hence the equation of the line CD is y = −3.

☆☞ Thus, AD = BC = Distance between AB and CD = (3 + 3) units = 6 units.

GOOD BYE!!!
