Let +x+ = the width
+3x+ = the length
----------------------------
The formula for perimeter, P, is:
+P+=+2W+%2B+2L+
+8.8+=+2x+%2B+2%2A%283x%29+
+8.8+=+8x+
+x+=+1.1+ km
-----------------------
The formula for area, A, is:
+A+=+W%2AL+
+A+=+x%2A%283x%29+
+A+=+3%2Ax%5E2+
+A+=+3%2A1.21+
+A+=+3.63+ km^2
--------------------------
If you want answer is square meters,
1000 m = 1 km
10^6 m = 1 km2
[ meters ] = [ meters / km ] * [ km ]
+10%5E6%2A3.63+=+3630000+
3,630,000 m2
