4th option is correct...

Answer 2

Required Answer :-

Quadrilateral ABCD is a rectangle.

AD = BC = 6 cm -(opp. sides of rectangle)

In ∆ CBE,

angle

B = 90°

Angle C = 60°

therefore,

Angle E will be 30° -(remaining angle)

Now,

By 30-60-90 theorem :-

side opposite to 30° is 1/2 of hypotenuse.

BC = 1/2 x CE

6 = 1/2 x CE

6 x 2 = CE

CE = 12 cm

therefore option A–12 cm is

correct ✅️
