The perimeter is a characteristic of a 2-dimensional object. A 12 by 13 by 5 sounds like a 3-dimensional object which would not have a perimeter.
With sides of 5 and 12, you can make a triangle with any perimeter you want between 24 and 34. If you call them "legs" because they are the sides of a right triangle, then the hypotenuse is 13, and the perimeter is 30.
perimeter = (5+5+12+12)= 34 area = (5*12) = 60 squared
Perimeter = distance around all 4 sides = 12 + 5 + 12 + 5 = 34 inches.
5 + 1 + 5 + 1 = 12 units.
A triangle has side lengths of 3, 4, and 5. The perimeter is 12 total. Perimeter is the total length of the outside of the object.
The perimeter of the triangle is: 13+12+5 = 30 inches

2.5ins, 6ins and 6.5ins respectively.The perimeter of a 5-12-13 triangle would be 30 in.The shortest side is 5/30 = 1/6 of the perimeter, the middle side is 12/30 = 2/5 and the biggest is 13/30.So, for the triangle with perimeter 15 inches, the smallest side is 1/6*15 = 2.5 inches.The middle side is 2/5*15 = 6 inches and the biggest side is 13/30*15 = 6.5 inches.
If it's a 12 by 5 rectangle then the perimeter is: 12+5+12+5 = 34 cm
The perimeter of a bedroom is the total distance around it. Like if one side is 12 feet, the others are all 13 feet. You would take 12+13+13+13=___. And that would be the Perimeter of your room. 51.
5, 12, 13 and 6, 8, 10
If that's a rectangle or a kite, then the perimeter is 50 feet.
The perimeter of the first one is 12 + 4 + 12 + 4 = 32 The perimeter of the second one is 13 + 3 + 13 + 3 = 32 So, yes, their perimeters have the same length.
Perimeter = distance around all 4 sides = 12 + 5 + 12 + 5 = 34 inches.
Since a parallelogram has opposite sides parallel and EQUAL, perimeter is 12+12+5+5 = 34 feet
13 - 12 + 5 = 6
