remote sensing - Extracting land cover type in Google Earth Engine?

I have a question related to Drawing polygon and extracting land cover inside using Google Earth Engine?

I'm trying to work out how to calculate habitat type area from within a specific polygon in google earth engine using Copernicus data. I can do both of these tasks, just not together.

var s1 = ee.ImageCollection("COPERNICUS/S1_GRD"),
S2 = ee.ImageCollection("COPERNICUS/S2"),

fc = ee.FeatureCollection("ft:1w_ciwxR9FKm0rzMH8oJ3MdyE-1U15PfiOFlGW5Ib"),
fc2 = ee.FeatureCollection("ft:18Xvf7jG2EI4mJMwj0oLV2u-05bAPiwJDaxSRy2ep");
//Set a point of interest 
var aoi = fc; 
//Set bands of interest
var bands = ['B2', 'B3', 'B4','B8', 'B11', 'B12'];

//Import and filter Sentinel 2 collection
var S2 = ee.ImageCollection('COPERNICUS/S2')
.filterDate('2016-07-01', '2016-08-01')

.filterBounds(aoi)
print(S2);
var image = S2.mosaic();

Map.addLayer(S2, {'bands': 'B12,B8,B4','min': 0,'max': 4000}, 'Sentinel 2A         SWIR,NIT,R', 0);
var training = image.sampleRegions(fc2, ["info"], 30);
var classifier = ee.Classifier.cart()
.train(training, "info", image.bandNames());
var out = image.classify(classifier);
Map.addLayer(out, {palette: [

'ff0000',// cleared red
'ffcc66',// cultivated
'387242',// forest 
'99ff33',// grass 
'e0e0d1',// rock 
'e0e0d1'// rock grass
], min:1, max:6});

// Create a geometry representing an export region.
var geometry =         ee.Geometry.Rectangle([36.977296602,-15.364411987,37.057018981,-15.447436229]);


Map.addLayer(ee.Image().paint(fc, 1, 3));
var fc = fc2;
Map.addLayer(fc2);

//Create a band for each veg type
var class1 = out.eq(1).select([0],['cleared']);
var class2 = out.eq(2).select([0],['cultivated']);
var class3 = out.eq(3).select([0],['forest']);
var class4 = out.eq(4).select([0],['grass']);

var class5 = out.eq(5).select([0],['rock']);
var class6 = out.eq(6).select([0],['rockgrass']);
// Concatanate the bands into a single image
var total = ee.Image.cat([class1,class2,class3,class4,class5,class6]);

// Extract the landcover band
var landcover = image.select('landcover');

 // Clip the image to the polygon geometry
 var landcover_roi = landcover.clip(geometry);


 //Calculate the total area of each veg type in meters^2
 var count = total.multiply(ee.Image.pixelArea());
 print(total);
 print(count);

 var area = count.reduceRegion(ee.Reducer.sum(), geometry, 30, null, null,        false, 1e10, 1)
print(area);
var cleared = ee.Number(area.get('cleared'));




Export.image.toDrive({ 
image: out,
description: 'imageToDriveDeforestation',
scale: 30,
region: geometry
 });
