In rectangle ABCD, two diagonals intersect at point O, if ∠ AOD = 120 ° AB = 2, find the perimeter of rectangle

In rectangle ABCD, two diagonals intersect at point O, if ∠ AOD = 120 ° AB = 2, find the perimeter of rectangle

Do 0m ⊥ ad after 0,
OM=1/2AB=1
∠MOD=60°
DM=1/2AD=tg60°OM=√3
Perimeter = 4 + 4 √ 3
