Step-by-step explanation:
Initial length be l.
Initial breath be b
Initial Area = l×b
After increasing,
New length = l+20% of l=l+

l
=
5
6l
New breath = b+20% of b=b+

New area =

Answer:
44%
Step-by-step explanation:
Initial length be l.
Initial breath be b
Initial Area = l×b
After increasing,
New length = l+20%of l=l+1/5=6/5l
New breath = b+20% of b=b+ b/3 =6/5b
New area = 36lb/25
% change in area =36lb / 25 -lb÷lb× 100
=11/25×100 =44%
