For a rectangle,
P=2%28L%2BW%29
2%28L%2B51%29=236
L%2B51=118
Now solve for L.

The formula for perimeter of
a rectangle is:
+P+=+2L+%2B+2W+
-----------------
given:
+P+=+236+ m
+W+=+51+ m
-----------------
+236+=+2L+%2B+2%2A51+
+2L+=+236+-+2%2A51+
+2L+=+236+-+102+
+2L+=+134+
+L+=+67+
The length is 67 m
-------------------
check:
+P+=+2L+%2B+2W+
+236+=+2%2A67+%2B+2%2A51+
+236+=+2%2A%28+67+%2B+51+%29+
+236+=+2%2A118+
+236+=+236+
OK
