Let +A%5Bp%5D+ = area painted pink
Let +A%5Bb%5D+ = area painted blue
(1) +A%5Bp%5D+=+4%2AA%5Bb%5D+
(2) +A%5Bp%5D+%2B+A%5Bb%5D+=+5+ m2
------------------------
(2) +4%2AA%5Bb%5D+%2B+A%5Bb%5D+=+5+
(2) +5%2AA%5Bb%5D+=+5+
(2) +A%5Bb%5D+=+1+
and
(1) +A%5Bp%5D+=+4%2AA%5Bb%5D+
(1) +A%5Bp%5D+=+4%2A1+
(1) +A%5Bp%5D+=+4+
The area painted pink is 4 m2
