given:
(1) +690+=+7L+%2B+4W+
(2) +228+=+2L+%2B+2W+ ( formula for perimeter )
----------------------
(2) +114+=+L+%2B+W+
Multiply both sides of (2) by +4+ and
subtract (2) from (1)
(1) +7L+%2B+4W+=+690+
(2) +-4L+-+4W+=+-456+
----------------------
+3L+=+234+
+L+=+78+
and
(2) +L+%2B+W+=+114+
(2) +W+=+114+-+78+
(2) +W+=+36+
----------------
The court is 36' x 78'
