Answer 1

Answer:

if it helped then mark my answer as brainliest

Step-by-step explanation:

let, a side of the square is x

after, increased by 30% it will be (x+30%)

=(x+0.3)

at the first time the area of the square is x^2

after increasing the area is (x+0.3)^2

=x^2+0.6x+9

so, the change of the area is (x^2+0.6x+9-x^2)

=0.6x+9

I can give percent of change of area after knowing the value of x.

hope it helped
