The perimeter (P) of a rectangle is the sum of the length's of all four sides which can be simplified by using the length (l) and width (w) as follows: P = 2*w+2*l.

It depends on the size....circumference is the length of the sides (combined) so it just depends how big the rectangle is
Circumference. If you have a rectangle, then the circumference (length of the sides) is equal to 2*height + 2*width.
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
There is no definitive answer for this question. There are actually an infinite number of valid answers, depending completely on the proportions of the 20-acre rectangle.The shortest possible distance around a 20-acre rectangle is 3,733.52 feet; in this case the rectangle is actually a square that is 933.38 feet on a side. Every other possible rectangle would have a longer circumference.ExamplesA rectangle that measures 500 feet by 1,742.4 feet would enclose 20 acres; it would have a circumference of 4,484.8 feet.A rectangle that measures 200 feet by 4,356 feet would enclose 20 acres; it would have a circumference of 9,112 feet.A rectangle that measures 50 feet by 17,424 feet would enclose 20 acres; it would have a circumference of 34,948 feet.As these examples illustrate, the distance around the 20-acre rectangle increases dramatically as the rectangle becomes farther from square. In fact, the upper limit of the circumference would be defined as "approaches infinity" as the short sides of the rectangle approach zero in length.
