You can put this solution on YOUR website!
Let the length = +x+ ft
The width = +x+-+5+ ft
+2x+%2B+2%2A%28+x+-+5+%29+=+50+
+2x+%2B+2x+-+10+=+50+
+4x+=+60+
+x+=+15+
and
+x+-+5+=+10+
--------------------
The dimensions are 15 x 10 ft2
-----------------------------
check:
+2x+%2B+2%2A%28+x-5+%29+=+50+
+2%2A15+%2B+2%2A10+=+50+
+30+%2B+20+=+50+
+50+=+50+
OK
