Let side of Square be “x” units
Original Area of the Square will be “ x² ” squ
10% increase in side will be (x*110/100) that is 11x/10 units
Hence changed length = 11x/10 units
Area of square with changed sides =121x²/100 squ
that is 21% increase in Area.
Hope it helps…

. If each side of the square is 10", then the area is 100 sqaure inches
.
If each side is increased by 10%
each side will be 11,
11 x 11 = 121
equals 121x² /100 square
inches. - an increase of
21%.
