One side of the rectangle has been reduced by 40% and the other has been enlarged by 60%.

To complete this task, you need to find out whether the area of the rectangle has increased or decreased.

Let’s consider this condition and analyze it.

By the terms of the assignment, we know that one side was reduced by 40%, and the other was increased by 60%.

So the original length of the sides of the rectangle was 100%, so we can write that the new length is equal to;

100 – 40 = 60%;

100 + 60 = 160%;

Or:

60% = 0.6;

160% = 1.6;

Let’s find the area of this rectangle in shares;

S = 0.6 * 1.6 = 0.96 * 100 = 96%;

100 – 96 = 4% the area of the rectangle has decreased.
