If each of the dimensions of a rectangle is increased by 200%, the area is increased by
Let dimensions of the rectangle are x and y respectively.
Then, Area = xy
After increment dimensions = (x + 200% of x) and (y + 200% of y)
= 3x and 3y
= Then, new area = (3x) (3y) = 9xy
= Increment in area = 9xy - xy = 8xy
∴ Required percentage = `(8xy)/(xy)xx100`% = 800%
