Description for Correct answer:
Increase in area
\[ \Large =25+25+\frac{25 \times 25}{100} \]
use formula \[ \Large [x+y+\frac{xy}{100}] \]
\[ \Large =50+6.25=56.25\% \]

Solution[By Examveda Team]
Suppose length of sq is “x”Then its area is x2
Now increase is side by 25%
Therefore x + x of 25% = 5x/4
And it's area = 25x2/16
Increase in area x2 - 25x2/16 = 9x2/16
Percentage in area increase = 56.25%
Which side of a square is increased by 25% find the percentage change in its area?
x+x+x×x100=2x+x2100=25+25+25×25100=56.25%
What will be the increase in area if the side of a square is increased by 30?
∴ The area is increased by 69%.
What is the percentage increase in area when the square length increased by 20%?
percentage increase in are =44%
What is the area of a regular square having a side of 25 cm?
We know that the area of a square is given by s 2 , where s = length of the side. It is given that the side s = 25 cm. Therefore, Area = s 2 = 25 × 25 = 625 sq.
