    meters of border required = 31.4 meter

    Step-by-step explanation:

    width/breadth of rectangular poster = 8 3/10 = 83/10 meters

    length of rectangular poster = 7 2/5 = 37/5 meters

    meters for border for the rectangular poster = perimeter of the poster

    = 2 (L+b)

    = 2 (37/5 + 83/10)

    LCM = 10

    = 2 (74/10 + 83/10)

    = 2 X 157/10

    = 31.4 meter
