You can put this solution on YOUR website!
Same y-value:
( 28, 40 )
( 8, 40 )
The x distance across is +28+-+8+=+20+
Same x-value:
( 18, 64 )
( 18, 16 )
The y distance top to bottom is +64+-+16+=+48+
———————-
+20%2F2+=+10+
+48%2F2+=+24+
+c+=+sqrt%28+10%5E2+%2B+24%5E2+%29+
+c+=+sqrt%28+676+%29+
+c+=+26+
This is the length of one side, so
+4%2A26+=+104+ is the length of tape
