Problema Solution
If the dimensions of a rectangle are increased by 100%, then the area of the rectangle is increased by what percent?
Answer provided by our tutors
Let 'x' and 'y' represent the original dimensions.
The area of the original rectangle is: A = xy.
The increased by 100% dimensions are: 2x and 2y.
The area of the increased rectangle is: A1 = 2x*2y = 4xy
A1/A = 4xy/xy = 4 or 400%
The area of the rectangle is increased by 400%.
