Answer is : decreased by 1%
Explanation :
Suppose
Length is 10cm.
Breadth is 20cm.
Then old Area = Length x Breadth = 10×20 = 200 ......................(i)If Length increased by 10% = 11cm
if Breadth decreased by 10% = 18cm
So, new Area = 11×18= 198 ..............................(ii)From (i) and (ii)
old area = 200
new area = 198
So new area is decreased by 1%
