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 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


The length of a rectangle is 12 inches. The width of the rectangle is 8 inches. find the perimeter of the rectangle?

The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches


Do you have to divide the area of a square by 2 to get the perimeter?

No. You have to take the square root of the area and then multiply that by 4. For example, if the area is 25, then the perimeter is 5 x 4 = 20.
