The formula is:
P+=+2w+%2B+2l
given:
P+=+244
l+=+w+%2B+42
------------
244+=+2w+%2B+2%2A%28w+%2B+42%29
244+=+2w+%2B+2w+%2B+84
4w+=+244+-+84
4w+=+160
w+=+40 in
and
l+=+w+%2B+42
l+=+40+%2B+42
l+=+82 in
The width is 40 in and the length is 82 in
check answer:
P+=+2w+%2B+2l
244+=+2%2A40+%2B+2%2A82
244+=+80+%2B+164
244+=+244
OK
