Problem in resizing the image

I resized the image to 300 * 300 using following code
im = imread('E:\flower1\img.jpg');
k=imresize(im,[300,300]);
imwrite(k,'E:/flower1/aa.jpg','jpg');
But when I read the image
>> x=imread('e:\flower1\aa.jpg');
[r1 c1]=size(x);
>> r1
r1 =
300
>> c1
c1 =
900
I am getting no of columns 900. Can anybody explain tell me why this is 900?

At a guess, given the tell-tale factor of 3 difference, I would say this is because it is saved as a true RGB image and it has 3 dimensions, not 2. In your case its dimensions are actually
300 * 300 * 3;
The 3 being the RGB dimension.
[a, b, c] = size( x );
should show this, but if you do not give enough outputs for all dimensions to the size function it will just roll up the remaining dimensions into the last one you give as an output argument.
