Given Length+=+2%2AWidth
Perimeter is 192. It is the sum of the sides. A rectangle has two sets of equal length sides.
Perimeter+=+2%2ALength+%2B+2%2AWidth
Perimeter+=+2+%2A%282%2AWidth%29+%2B+2%2AWidth
192+=+2%2AWidth+%2B+2%2AWidth
192+=+6%2AWidth
32+=+Width
Length = 2*Width = 64
Check your answer, does 64+64+32+32 = 192?
