Since 2m is left on all sides, thus,
Length of hall = 38m
Breadth of hall = 22m
Area = 38x22 = 836 sq.m
Length of carpet = 6m
Breadth of carpet = 4m
Area = 6x4 = 24 sq.m
No of carpets = (38x22)/(6x4) = (11x19)/6
= 34 5/6
= 35 carpets
Hope it helps :)

After leaving the border,
Area of the hall to be carpeted
= (40 - 4)(24 - 4) = 720=(40−4)(24−4)=720
Area of each carpet
= 6 \times 4 = 24=6×4=24
No. of carpeta required =
\frac{720}{24} = 3024720=30
