Draw nine rectangles, with the following dimensions:1 by 172 by 163 by 154 by 145 by 136 by 127 by 118 by 109 by 9If you want to get the jump on the next topic coming up in math, thenwhile you're drawing these rectangles, notice that even though theyall have the same perimeter, they all have different areas.

10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2

Infinite in number, from a 4 x 4 square to 0.0000001 x 7.9999999 etc

Perimeter: add all sides area: multiply length times width for rectangles

There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.

You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.

The area doesn't tell you the dimensions or the perimeter. There's an infinitenumber of rectangles that all have the same area but different perimeters.The smallest perimeter that encloses 13 acres is a circle with diameter of 849.12 feet,and perimeter (circumference) of 2,667.6 feet.The smallest possible perimeter of a rectangle that encloses 13 acres is squarewith sides of 752.5 feet, and perimeter of 3,010.1 feet .You can draw 13-acre rectangles with any perimeter you want that's larger than that.Here are a few. These all enclose 13 acres.60' x 9,438' . . . perimeter = 18,996'120' x 4,719' . . . . . 9,678'143' x 3,960' . . . . . 8,206180' x 3,146' . . . . . 6,652'360' x 1,573' . . . . . 3,866'429' x 1,320' . . . . . 3,498'660' x 858' . . . . . . 3,036'

There are infinitely many possible rectangles. Let A be ANY number in the range (0,6] and let B = 12-A. Then a rectangle with width A and length B will have a perimeter of 2*(A+B) = 2*12 = 24 units. Since A is ANY number in the interval (0,6], there are infinitely many possible values for A and so infinitely many answers to the question.
