What is the perimeter of a room 10 ft by 11 ft?
I would assume it to be 42 ft depending if you are talking about the inside of the room or the outside perimeter
What is the perimeter of a regular pentagon with 8 ft sides?
40 ft.
Which has the larger perimeter a 16-foot by 26-foot rectangle or a 20 foot square?
Perimeter of [ 16 x 26 ] rectangle = 16 + 16 + 26 + 26 = 84-ft . Perimeter of a 20-ft square = 4 x 20 = 80-ft . The rectangle has the greater perimeter.
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.
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
