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 is the perimeter of a square with an area of 121 square ft?
Area = side^2 side = √121 = 11 ft Perimeter = 4 x side = 4 x 11 = 44 ft.
What is the perimeter of a room 40 ft by 16 ft?
40ft + 40ft + 16ft + 16ft = 112 ft
What is the perimeter of a room with an area of 169 square feet?
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
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
