The two rectangular areas have the same area. Length 1 – 48 m, width 30 m.

The two rectangular areas have the same area. Length 1 – 48 m, width 30 m. Compare the perimeters of these sections, if it is known that the width of the 2nd section is 6 m of the width of the 1st?

Let’s find the width of the second section:

30 + 6 = 36 meters.

The width of the second section is 36 meters.

Let’s calculate the area of the first section:

48 * 30 = 1440 m².

The area of the first plot is 1440 m², which is equal to the area of the second plot. From here we can find the length of the second section:

1440: 36 = 40 meters.

The second section is 40 meters long.

Let’s find the perimeter of the first section:

2 * (48 + 30) = 156 meters.

Let’s find the perimeter of the second section:

2 * (36 + 40) = 152 meters.

156 – 152 = 4 meters.

Answer: the perimeter of the second section is less than the perimeter of the first section by 4 meters.
