The length of the rectangle is 35cm and the width is 20cm. We built a new rectangle, the length of which is 5cm longer and the width is 5cm less. Is the area of the new rectangle equal to the area of the given rectangle? if not, how many square centimeters is the area of the new rectangle more or less than the area of the given one?

Determine the area of the first rectangle as the product of its length and width:

35 * 20 = 700 (cm2).

To determine the area of the second rectangle, we will find its length and width, taking into account that these dimensions are 5 cm larger than the dimensions of the first rectangle. The length of the rectangle will be:

35 + 5 = 40 (cm).

The width of the rectangle will be:

20 + 5 = 25 (cm).

Find the area of the second rectangle:

40 * 25 = 1000 (cm2)

Let’s compare the areas of the rectangles and find their difference:

700 <1000.

1000 – 700 = 300 (cm2).

Answer: The area of the second rectangle is 300 cm2 larger.
