How many meters of border will be needed for a rectangular poster 8 3/10 meters wide and 7 2/5 meters long

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
