The width of the rectangular piece of land is 25 m, and the length is 15 m longer.

The width of the rectangular piece of land is 25 m, and the length is 15 m longer. How and how will the area of the site change if its width is increased by 7 m, and the length is reduced by 5 m?

1) Find the length of the first section.

We add another 15 meters to the width.

Will:

25 + 15 = 40 m.

2) Find the length and width of the second section.

If you reduce the length by 5 meters, it will be:

40 – 5 = 35 meters.

If the width is increased by 7 meters, it will be:

25 + 7 = 32 meters.

3) Find the area of two sites.

We multiply the width by the length.

25 * 40 = 1000 m2 (area of the first plot).

32 * 35 = 1120 m2 (area of the second site).

4) Find the difference in the area of the plots.

1120 – 1000 = 120 m2

Answer:

The land area will increase by 120 m2
