How many times will the area of a rectangle decrease if its length is reduced by 5 times, and its length by 2 times?

Let’s write down the formula for the area of a rectangle: S = a * b;

You can think of it as the area value of the original rectangle.

Let’s write down the new dimensions of the rectangle:

a) the length will decrease by 5 times, i.e. a: 5 = a / 5;

substitute in the formula S1 = b * a: 5 = S: 5 – will decrease by 5 times.

b) the length will decrease by 2 times, i.e. a: 2 = a / 2;

substitute in the formula S1 = b * a: 2 = S: 2 – will decrease by 2 times.
