Crux In Finding Magnetic Flux

A infinitely long wire carry a current of $I$ $A$ . A regular hexagon of side length $1m$ placed in the same plane of wire at a perpendicular distance of $1m$ from its nearest side to the wire. Calculate the total flux passing through the hexagon. If your answer is in the form of $\frac{a\mu_{o}I}{2π}$ . Find $a$ upto two decimal places. If your answer comes in the form $1.9873$ . Type it as $1.98$
