a .its length is doubled
b. its length is halved​

Answer 1

Step-by-step explanation:

a.its length is doubled

Answer 2

when halvedAnswer:

a)area becomes 4 times the normal are

b)the area becomes 1/4th of the area earlier

Step-by-step explanation:

let length be s

area=s*s=s^2

when doubled

2s*2s=4s^2

which in comparison is 4 times the regular area

when halved

s/2*s/2=s^2/4

which in comparison to normal area is 1/4th

hope this solves your problem
