16 feet.
The perimeter is the sum of the three sides.
Assuming you mean a rectangle: use the formula:p = 2(l+w) (i.e., perimeter equals twice length plus width). In this formula, replace p with the known perimeter, and l with the given length, then solve for width.
Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm
The law of tangents can be used to determine another side length; the sine rule can then be used to determine the third side length.
Cylinders are circles pulled out into the third dimension and rectangular prisms are rectangles pulled into the third dimension.
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
The perimeter is the sum of the three sides.
With the amount of information given in the question, it is not possible.

You cannot discover the perimeter of a triangle if all you have is the length of two sides and nothing else. Knowing only the length of two sides of a triangle is insufficient to discover the length of the third side, and, thereby, discover the perimeter.

Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm
The second and third rectangular numbers are 6 and 12
the perimeter of a triangle is 86 inches. the largest side is four inches less than twice the smallest side. the third side is 10 inches longer than the smallest side. what is the length of each side?
OK, so let's say the length of the base = x. The leg length = 3x, as it's three times the base length. As there are two legs and a base making up the perimeter, the perimeter = 10x. So 62 = 10x. 62/10 = 6.2, therefore x = 6.2 and the base = 6.2 inches. Hope this helps! If base = x and each leg = 3x, then the perimeter would be 7x instead of 10x as mentioned above. (3x + 3x +x = 7x). Hence, perimeter = 7x and the base (x) = 8.857 inches.
The law of tangents can be used to determine another side length; the sine rule can then be used to determine the third side length.
