Answer:

answer: 3) 21 %

Explanation:

Let the original length of the sides be x(which of 100%)

Now if we increase the length by 10%,then:

=>110% of x

=> 11x/10

Original Area = x square

New Area = (11x/10) square

= 121x square/100

To find the increase in area :

we have to find the difference in original area- new area.

(121x square /100)-x square

21xsquare/100

[x square is of 100%]

Increase by % :

= 21xsquare /100*1/x square*100

= 21%
