What is the perimeter of a regular nonagon with a side measuring 21 ft?
189 feet.
What is the perimeter of a room that is 12 ft long and 10 ft wide?
The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the room is 12 feet long and 10 feet wide. To find the perimeter, you add the length of all sides: 12 + 12 + 10 + 10 = 44 feet. Therefore, the perimeter of the room is 44 feet.
A rectangle had an area of 24ft2 what is the length and width of the rectangle with the greatest perimeter?
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.
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 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
How do you find the perimeter of 3ft by 5 ft?
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
What is the perimeter of a regular pentagon with sides that are 3 ft long?
15 ft.
What is the perimeter of a regular pentagon with 8-ft sides?
It is: 5*8 = 40 feet
What is the perimeter of a regular pentagon with a side length of 10 ft?
50 ft
What is perimeter of a pentagon that is 2ft on all sides?
5*2 ft = 10 ft
What is the perimeter of a square with sides measuring 27 ft?
The perimeter of a square is calculated by adding the lengths of all four sides. Since all sides of a square are equal, the formula for the perimeter is P = 4 × side length. For a square with sides measuring 27 ft, the perimeter would be P = 4 × 27 ft = 108 ft. Therefore, the perimeter of the square is 108 feet.
What is the least possible perimeter with an area of 169 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.
Find the perimeter of pentagon that has edges of 8 ft 6 ft 4 ft 10 ft and 5 ft?

Which triangle is similar to An equilateral triangle with perimeter 60 ft?
An equilateral triangle with a perimeter of 60 ft has all three sides equal, each measuring 20 ft. Any triangle that is also equilateral and has sides in the same ratio will be similar to it. For example, an equilateral triangle with a perimeter of 30 ft (sides of 10 ft each) or one with a perimeter of 90 ft (sides of 30 ft each) would be similar, as they maintain the same angle measures and the ratio of their corresponding sides is consistent.
What is the perimeter of a rhombus with sides that are 4.72 ft long?
That rhombus has a perimeter of 18.88 feet.
What would be the area of a regular polygon with the perimeter of 20 ft and apothem of 3 ft?
Area of regular polygon: 0.5*20*3 = 30 square feet
What is the perimeter of the rectangle 11 ft by 21 ft?
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
