The length of the rectangle is 8.5 dm and the width is 6 dm. How many times will the area of a rectangle

The length of the rectangle is 8.5 dm and the width is 6 dm. How many times will the area of a rectangle decrease if its width is reduced by 2 dm?

The area of a rectangle is calculated by multiplying its length by its width. Let’s calculate the area of the original rectangle:

S = 8.5 dm * 6 dm = 51 dm2.

The width of the rectangle has been reduced by 2 dm, we find it:

6 – 2 = 4 dm.

Find the area of the reduced rectangle:

S = 8.5 dm * 4 dm = 34 dm2.

Let’s calculate how many times the area has decreased:

51: 34 = 1.5 times.

Answer: the area of the rectangle has decreased by 1.5 times.
