The width of the rectangle is 25 cm.How much will the area of this rectangle increase if its length

The width of the rectangle is 25 cm.How much will the area of this rectangle increase if its length is increased from 30 to 35.

1. The area of a rectangle is equal to the product of the length of this rectangle by its width. If a given rectangle has a width of 25 centimeters and a length of 30 centimeters, then its area is:

25 x 30 = 750 cm ^ 2.

2. If the length of the rectangle is increased from 30 centimeters to 35 centimeters, then the area of the resulting rectangle will be equal to:

25 x 35 = 875 cm ^ 2.

3. Let’s calculate how much the area has increased:

875 – 750 = 125 cm ^ 2.

Answer: the area of the rectangle will increase by 125 cm ^ 2 if its length is increased from 30 centimeters to 35 centimeters.
