If the length of a rectangle is increased by 14.28 percent then by how much percentage its breadth should be reduced to keep the area same?

Given:
Length increased by 14.28%, New length = 8 units (original 7 units)
Formula Used:
% decrease in breadth = (Old Breadth - New Breadth) / Old Breadth × 100
Solution:
14.28% → 1/7
Length changes from 7 to 8.
Breadth changes from 8 to 7.
Percentage decreased in breadth size = {(8 - 7)/8} × 100 = 12.5% ​​​​
