| Let us denote through the variable n the initial length of the rectangle, through the variable m the initial width of this geometric figure.

Accordingly, the area of the original rectangle will be: n * m.

Let’s calculate what the length of the new geometric figure will be:

n + n * 30/100 = 1.3n.

Let’s calculate what the width of the new geometric shape will be:

m – m * 60/100 = 0.4m.

Let’s calculate what the area will be equal to:

1.3n * 0.4m = 0.52mn.

Answer: The area of the new figure is 0.52 of the area of the old one.
