Answer 2

Answer:

144%

Step-by-step explanation:

say L and B the length and breadth of original plot

area of original plot

AREAorginal=LB

not after increasing L and B by 20%

Lnew=0.2L+L=1.2L

Bnew=0.2B+B=1.2B

area of new plot

AREAnew=(1.2L)×(1.2B)=1.44LB

now

AREAorginal/AREAnew=LB/1.44LB

=1/1.44

thus,

AREAnew=1.44 times AREAorginal

thus percentage increase in area=144%
