My apologies there isn't a chemistry option hence i could only post it under maths.

But may i know if is possible to draw both the Br of product with wedge bond or both Br with bolded bond? Is the answer still correct in this case? Thank you!

Wedge refers to the bold triangular markings.
The dotted ones are dashes.

In such a bromination you have 'anti' stereochemistry due to the bromonium ion formation, and the subsequent attack by the other bromine ion from the opposite side of the C-Br bond.

If you draw both wedges, or both dashes, it would be incorrect because that would be the 'syn' conformation, which does not adhere to the mechanism
