we can handle the problem with the help of following solution .
For every Rectangle Length is Longer than it"s Breadh.
Let Length of Rectangle =10cm& Breadh =6cm
Area of Rectangle =LENGTHxBREADH
Area=10cmx6cm=60sq cm
According to question
Length of Rectangle increased by 1=(10+1)cm =11cm & Breadh decreased by 1=(6-1)cm=5Cm
Area of New Rectangle= 11cmx5cm=55sqcm
55sqcm<60sq cm New area will be decreased.
