You can't tell the individual side lengths from the perimeter. The only thing
you can tell for sure is that they add up to 27.
There are an infinite number of different triangles that all have 27 as their
perimeter.
Here are a few of them:
1, 2, 24
2, 4, 21
4, 8, 15
5, 8, 14
6, 8, 13
6, 9, 12
6, 10, 11

etc.
The perimeter of the equilateral triangle is 3 times 4 = 12 cm
9ft
That depends on the size of the angles which, in turn, determines the geometry of the triangle.
Doubling the side lengths of a right triangle results in a new triangle with each side being twice as long. Since the perimeter is the sum of all the side lengths, doubling each side effectively doubles the perimeter as well. Therefore, if the original perimeter is ( P ), the new perimeter will be ( 2P ).
36 inches
12 feet
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Assuming the triangle is an equilateral triangle, each side is equal to 42/3 = 14 millimetres long. Increasing the sides by 50 percent makes each side 14 x (1 + 50/100) = 14 x 1.5 = 21 millimetres. Therefore, the perimeter of this new triangle will be 21 x 3 = 63 millimetres.
They are 12.5 cm each.
If the perimeter of a triangle is 234 cm, then the sum of the lengths of all three sides is 234 cm. Since a triangle has three sides, each side would be one-third of the perimeter. Therefore, each side of the triangle would be 234 cm divided by 3, which equals 78 cm.
The perimeter of a triangle is the sum of lengths of each side. So the perimeter would be 13 cm + 13 cm +10 cm = 36 cm
