You should be able to recover that disk space by deleting the Windows partition from within the Boot Camp Assistant. This should restore your disk to a single partition drive. There is more information about removing Boot Camp on Page 10 of the manual:
Remove Windows from your Mac
How you remove Windows from your Mac depends on whether you installed Windows on a second partition or on a single-volume disk.
If you installed Windows on a second disk partition: Using Boot Camp Assistant as described below, remove Windows by deleting the Windows partition and restoring the disk to a single-partition OS X volume.
If your Mac has multiple disks and you installed Windows on a disk that has only one partition:
Start up in OS X and use Disk Utility, located in the Other folder in Launchpad, to reformat it as an OS X volume.
1 Start up your Mac in OS X.
2 Quit all open apps and log out any other users on your Mac.
3 Open Boot Camp Assistant.
4 Select “Remove Windows 7,” then click Continue.
5 Do one of the following:
• If your Mac has a single internal disk, click Restore.
• If your Mac has multiple internal disks, select the Windows disk, select “Restore to a single
Mac OS partition,” then click Continue.
