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.
