If length and breadth of a rectangle became half and double respectively, then what will be the resultant area ?
-
- 25%
- 55%
- 75%
- 80%
- None of the above
Correct Option: E
According to the question,
Change in length of rectangle = - 50% = a
Change in breadth of rectangle = 100% = b
Net effect = a + b + (ab)/100 %
= - 50 + 100 + [(-50) (100) / 100]%
= 0%
