Question 327618
Let the original length and breadth of the rectangle be l m and b m respectively.
On changing, the new dimensions become l - 14 and 2b.
Given, l - 14 = 2b = 84/4 = 21
=> l - 14 = 21 
=> l = 21 + 14 = 35
2b = 21 m
b = 21/2 = 10.5m
Hence, the original length and breadth of the rectangle are 35 m and 10.5 m
