The rectangle with the smallest perimeter for a given area is the square. The rectangle with the greatestperimeter for a given area can't be specified. The longer and skinnier you make the rectangle, the greater its perimeter will become. No matter how great a perimeter you use to enclose 24 ft2, I can always specify a longer perimeter. Let me point you in that direction with a few examples: 6 ft x 4 ft = 24 ft2, perimeter = 20 ft 8 ft x 3 ft = 24 ft2, perimeter = 22 ft 12 ft x 2 ft = 24 ft2, perimeter = 28 ft 24 ft x 1 ft = 24 ft2, perimeter = 50 ft 48 ft x 6 inches = 24 ft2, perimeter = 97 ft 96 ft x 3 inches = 24 ft2, perimeter = 192.5 ft 288 ft x 1 inch = 24 ft2, perimeter = 576ft 2inches No matter how great a perimeter you find to enclose 24 ft2, I can always specify a rectangle with the same area and a longer perimeter.
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 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe 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 ftA circle of circumference 20 ftThe 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 ftHowever, 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
Yopu can't tell the dimensions from knowing the area.-- The smallest possible perimeter would result from a circular room with diameterof 14 feet 8.03 inches. Then the perimeter is 46feet 1inch .-- If the room has straight sides, then the smallest possible perimeter results froma square room with 13-ft sides. Then the perimeter is 52feet.-- The perimeter can be anything greater than 52 feet. If the room is a rectangle,then the longer and skinnier it is, the greater the perimeter is.10-ft x 16.9-ftArea = 169 square feetPerimeter = 53.8 feet6.5-ft x 26-ftArea = 169 square feetPerimeter = 65 feet5-ft x 33.8-ftArea = 169 square feetPerimeter = 77.6 feet3.25-ft x 52-ftArea = 169 square feetPerimeter = 110.5 feet2-ft x 84.5-ftArea = 169 square feetPerimeter = 173 feet1-ft x 169-ftArea = 169 square feetPerimeter = 340 feet
16ft..A perimeter is the distance around a shape. So if this is a 3 by 5ft rectangle , considering it has four sides, you add them all up so:3+3+5+5= 16so the perimeter is 16ft
15 ft.
It is: 5*8 = 40 feet
50 ft
5*2 ft = 10 ft
The shape which minimises the perimeter for a fixed area is a circle. A circle of radius 7.334 ft (approx) will have the required area and a perimeter (circumference) of just 46.084 ft. The quadrilateral with the smallest perimeter will be a square with sides of 13 feet: a perimeter of 4*13 = 52 feet. Any regular polygon with more than 4 sides will have a smaller perimeter, for the same area, than a square.

That rhombus has a perimeter of 18.88 feet.
Area of regular polygon: 0.5*20*3 = 30 square feet
In a rectangle, the opposite sides are equal, so two sides are 11 ft and the other two are 21 ft. To find the perimeter of a rectangle, you only have to add up all sides. So it's 11 + 11 + 21 + 21 = 64 ft
The perimeter is the distance around the room, The reason the perimeter increased by 18 ft is due to both sides of the room that were lengthened by 9 ft.
By adding the perimeter of all of the sides.
