increased by 10%, then what
percent of the area of square will

Answer 1

Answer:

21%

Step-by-step explanation:

Let the original length of sides be x

Then, new length =(110% of x)=11x10

Original area x2

New area =(11x10)2=121x2100

Increase in area :=(121x2100−x2)=21x2100

∴ Increase % :

=(21x2100×1x2×100)%=21%
