Answer:
(x+7)÷5
Step-by-step explanation:
since the number is unknown, it becomes X. Because we first add 7 then divide by 5, the expression will be a bracketed (X+7), followed by the division by 5. This makes sense because of the BODMAS rule to which, in coherence with the BODMAS rule, we first solve the expression in the brackets then move on outside them.

If you take the perimeter, 24, and cut it in half, you are left with the sum of two sides of the rectangle. This is easier to manage. Now, make a list of numbers whose sum is 12. I got 1+11, 2+10, 3+9, 4+8, 5+7, 6+6
The other part of the problem said that the length is 3 times its width. look at the pairs of numbers, and is there a set the has one number that is three times larger than the other number in that same set? Yes, 3 and 9. (9 is three times larger than 3)
So, the length of the rectangle is 9 inches and the width is 3 inches.
