You can put this solution on YOUR website!
The perimeter of a square is the sum of lengths of the fours sides. Each side of a square has the same length.
You are told one side is 3x%2F4%2B1. So the perimeter is 4 times that
Perimeter+=+4+%2A++%28%283x%2F4%29%2B1%29
Perimeter+=+3x+%2B+4

2)The perimeter of a rectangle is the sum of lengths of the fours sides. Every rectangle has two sets of equal length sides.
You are told the length of one side is 18.
Perimeter+=+2%2ALength+%2B+2%2AWidth
50+=+2%2A18+%2B+2%2AWidth
50+=+36+%2B+2%2AWidth
14+=+2%2AWidth
7+=+Width
