Answer:
125% increase
Step-by-step explanation:
let the side of the square be y
A = side²
⇒y²
if y is increased by 50%,
then the number is 1.5 y ( 150% of y)
area = side² as mentioned above
⇒(1.5 y)²
⇒2.25 y²
2.25 when converted to percent = 225% (multiply by 100)
increase in area = 225% - 100% of y²
= 125 %
