A because we have to subtract 0.5 4 times (for the four sides) or in other words subtract 1 twice. If you think of it like this, then your answer will be A, 22.

b is correct as perimeter of the room is 26m and when the carpet is laid then 0.5 m is left. so we need to add 0.5 4 times for each side which is equal to 2m.so we subtract 2 from 26 and the answer will be 24m.

The correct answer is A as there are eight 0.5 m borders and the perimeter of the room is 26 m so 26 - 0.5 x 8 = 26-4 = 22 m.
