The area of the "aob" secor is given by:
 A = (S '/ S) * (pi) * (r ^ 2)
 Where,
 S '/ S = relation of arcs
 r: radius of the circle
 Substituting values we have:
 A = (145/360) * (3.14) * (2 ^ 2)
 A = 5.058888889
 Rounding off we have:
 A = 5.1 yd ^ 2
 Answer:
 the area of sector "aob" is:
 A = 5.1 yd ^ 2
