Area of rectangle =length×breadth
Given, Length = 40 m and breadth= 25m
Hence, area of the rectangle is 40m X 25m=1000sq.m
Given dimensions are increased by 15 percent.
Hence new length and breadth will be
Length= 15‰ of 40 and15‰ of 25
Hence new length = 46m
New breadth = 28.75
The new area is length*breadth is 46mX 28.75m
Area is 46 X 28.75=1322.5 sq.m
the increase in area is 1322.5 sq.m – 1000= 322.5 sq m
The percentage increase is 32.25%
