this is your answer please follow me

Answer 2

Answer:

225%

Step-by-step explanation:

given that

let actual side be x

the increase in side =x+50%=x+x/2=3x/2

actual area =(x)(x)=x sq

now the area is (3x/2)(3x/2)=9x/4

the ratio of increase = 9x/4/x=9/4=225/100

therefore the increase percentage of volume is 225%
