### How many feet in the perimeter of a 10 acre lot?

The area of a lot is not enough information to determine its
perimeter. The most compact perimeter is approx 740 feet, which is
attained by a circular lot.
Consider the following rectangular plots, each is of area 1
acre:
100 ft * 435.6ft : perimeter = 1071.2 ft
10 ft * 4356 ft : perimeter = 8732 ft
1 ft * 4356 ft : perimeter = 87122 ft
0.1 ft * 43560 ft : perimeter = 871200.2 ft
...
0.000001 ft * 43,560,000,000 ft : perimeter = 87,120,000,000 ft
(approx) = 16,500,000 miles.
There is virtually no limit to how much the first dimension can
be reduced and the perimeter increased.

### What is the perimeter of a half acre?

Half an acre = 21780 sq feet.
This could have a perimeter of any length greater than (or equal
to) 523.16 feet.
If the area is in the form of a circle of radius 83.26 feet, it
will have the minimum perimeter of 523.16 feet.
Or, you can have a square of 147.6 ft giving a perimeter of
590.3 ft,
or a rectangle of 150 ft * 145.2 ft - perimeter = 590.4 ft
or a rectangle of 100 ft * 217.8 ft - perimeter = 635.6 ft
or a rectangle of 10 ft * 2178 ft - perimeter = 4376 ft
or a rectangle of 1 ft * 21780 ft - perimeter of = 43562 ft
etc, with the perimeter increasing without limit.
Or, the area could be circular giving the minim
590 feet.

###### Asked in Math and Arithmetic

### How can two rectangles have the same perimeter and different area?

Easy.
Rectangle #1: 5-ft x 20-ft
Perimeter = 50-ft
Area = 100 square ft
Rectangle #2: 6-ft x 19-ft
Perimeter = 50-ft.
Area = 114 square ft
Rectangle #3: 7-ft x 18-ft
Perimeter = 50-ft
Area = 126 square-ft
Rectangle #4: 10-ft x 15-ft
Perimeter = 50-ft
Area = 150 square ft
Rectangle #5: 12-ft x 13-ft
Perimeter = 50-ft
Area = 156 square ft
Hi, this is Stacy Park and you can also do this:
2 ft x 5 ft
Perimeter = 14 units
Area = 12 units
Or this:
4 ft x 3 ft
Perimeter = 14 units
Area = 10 units

###### Asked in Math and Arithmetic, Algebra, Area

### What is the perimeter of 3 acres in ft?

The area is not sufficient information to determine the length
and width. First of all, there is no reason to suppose that the
area is rectangular as opposed to circular or triangular or some
other simple or complicated shape.
3 acres is 130,680 square feet. The smallest perimeter for 3
acres will be attained if it is a circular area with a perimeter of
1281.5 ft (approx). But there is no maximum, as can be seen from
the following:
The area could be in the form of a rectangle which is:
361.5 ft * 361.5 ft (approx) and a perimeter of 1,446 ft or
1,306.8 ft * 100 ft and a perimeter of 2,813.6 ft or
13,068 ft * 10 ft and a perimeter of 26,156 ft or
130,680,000 ft * 0.001 ft and a perimeter of 261,360,000.002
ft
and so on.

### What is the largest possible perimiter of a rectangle with an area of 25ft2?

The smallest possible perimeter is 20-ft, but
there is no largest possible perimeter.
You can make it as large as you want, with no limit.
Examples:
5-ft x 5-ft . . . . area = 25 ft2 . . . perimeter = 20 ft
2.5-ft x 10-ft . . area = 25 ft2 . . . perimeter = 25 ft
1-ft x 25-ft . . . area = 25 ft2 . . . Perimeter = 52 ft
6-in x 50-ft . . . area = 25 ft2 . . . Perimeter = 101 ft
3-in x 100-ft . . area = 25 ft2 . . . perimeter = 2001/2 ft
1-in x 300-ft . . area = 25 ft2 . . . perimeter = 6001/6 ft
0.1-in x 3,000-ft . . area = 25 ft2 . . . perimeter = 6,0001/60
ft

###### Asked in Math and Arithmetic, Algebra, Geometry

### What would the perimeter of a 20ft semicircle be?

That depends on what you mean by a "20 ft semicircle".
A semi-circle is a half circle.
A 20 ft circle could be:
A circle of diameter 20 ft
The perimeter of the semicircle is half the circumference plus the
diameter
→ perimeter = 1/2π 20 ft + 20 ft
= 10π + 20 ft
≈ 51.42 ft
A circle of radius 20 ft
The perimeter of the semicircle is half the circumference plus
double the radius
→ perimeter = 1/2 2π 20 ft + 2 x 20 ft
= 20π + 40 ft
≈ 102.08 ft
A circle of circumference 20 ft
The perimeter of the semicircle is half the circumference plus the
diameter
→ perimeter = 1/2 20 ft + 20 ft ÷ π
= 10 ft + 20/π ft
≈ 16.37 ft
However, if a 20 ft circle is a circle with a circumference (=
perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle
with a perimeter of 20 ft
→ perimeter = 20 ft

-- Length = 16-ft, Width = 12.5-ft
-- Area = 200 square ft
-- Perimeter = 57-ft
Rectangle C:
-- Length = 40-ft, Width = 5-ft
-- Area = 200 square ft
-- Perimeter = 90-ft
Rectangle D:
-- Length = 50-ft, Width = 4-ft
-- Area = 200 square ft
