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.
100 - (2 x 36) = 28 cm
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.
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. Use the link below to a related question and see how it works.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
Oh, dude, if you take a square and shrink each side to one-third of its original length, the perimeter will decrease by a factor of three. It's like those magic tricks where things disappear, but in this case, it's just basic math. So, if the original perimeter was 12 units, it would become 4 units after the sides were reduced. Easy peasy!
