Answer 2

Answer:

82.25%

Step-by-step explanation:

let original side be x.

Therefore, original area is $x^{2}$.

length of side when increased 35% =  $x*\frac{100+35}{100}=135/100x$

Therefore, area when increased = (135/100)$\frac{135}{100} ^{2} x^{2} =18225/10000x^{2}$

Therefore,percentage increase of area = (18225/10000)-1=82.25%
