Answer 1

Answer:

Step-by-step explanation:

Let original length = x metres and original breadth = y metres.

Original area = xy sq.m  

Increased length  = 120100 and Increased breadth = 120100  

 

New area = 120100x*120100y=3625xy m2  

 

The difference between the Original area  and New area  is:  

3625xy−xy

 

1125xy Increase % =(1125xyxy/)*100= 44%
