Best ResponseYou've already chosen the best response.2it means here u hav to increase or add the that fraction (10/100) to the initial edge of square

Best ResponseYou've already chosen the best response.2now 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

Best ResponseYou've already chosen the best response.0Area 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.
