perimeter of the floor=17cm
height of the wall=4m
perimeter/2 of the wall=lenght + bredth of wall
(perimeter=2(l+b)
so to get only lenght and breadth we should divide 2 with perimeter)
Now,perimeter=17/2=8.5cm
convert 4m into cm =4×100=400cm
area of four walls (CSA of cuboid)=2h(l+b)
=2×400(8.5)
=6800sq.cm
