Answer:
The answer is 18.
Step-by-step explanation:
Perimeter is P, length is L, and width is W. So, P is L plus L plus W plus W. If L is 30, then L plus L is 60. Do the P minus 60, which is 36. So, to find width, use that.
W plus W is the last part of P, and P minus 60 is 36. So, for one width, it is 36 divided by 2, which is our answer: 18.
