    'by' means certain fraction of total is increased or decreased here in this case it is increased

    it means here u hav to increase or add the that fraction (10/100) to the initial edge of square

    that is 10/100 = 0.1 (fraction of total )

    now see let us suppose we hav the edge of sq. initially be 1 ..then by the defination of 'by' that i hav told u above u can add fraction (0.1) to 1 that is nw the final edge length is 1.1

    Area of square with edge a is a². Edge of new square is a+10% of a = a + 0.1a = 1.1a. Area of new square is (1.1a)²=1.21a² = a² + 0.21a² = a² + 21% of a². So it is 21 % more.

    @manishsatywali : Just thought you had done enough to explain. Sometimes it is better to write the whole thing down, to show the steps. If I had done this right away, I would agree with you ;)
