The percentage increase in the area of a rectangle, if each of its sides is increased by 20% is

A. 44%

B. 45%

C. 34%

D. 35%

Correct Answer : A.


Let original length = x metres and original breadth = y metres
Original Area=xy m2
New Length =120100x=65x
New Breadth=120100y=65y
⇒New Area=65x * 65y   
⇒New Area=3625xy
Area Difference=3625xy−xy                            
=1125xy
Increase%=DifferenceActual * 100   
=11xy25 * 1xy * 100
=44%
