Question

The side of a square is increased by 35./. . find the percentage gain in area

Answer 1

Step-by-step explanation:

Assume the side of square be x

Then increase in side is 35%

so new side will be

$x + 35\% \: of \: x$

i.e

x + 35/100 × x

$x + 0.35x \\ = 1.35x$

Then the new side wI'll be

1.35x

now area when side is x= x²

Now area when side is 1.35x=

$1.35x \times 1.35x = 1.8225 {x}^{2}$

so increase in area = 82.25 %

Thus your answer is

82.25%
