If an equilateral triangle is 3 centimeters long then the perimeter of the triangle is 9 centimeters. The perimeter is found by adding up the lengths of all the sides of an object.
each side is equal to 16 cm 16 + 16 + 16 = 48 cm
Its perimeter is: 4*3.5 = 14 cm
18.9 cm.
3*8 cm = 24 cm.
The dimensions given would be appropriate for an equilateral triangle.
The perimeter of the equilateral triangle is 3 times 4 = 12 cm
In an equilateral triangle, all sides are of equal length. So sum of three equal sides is 42 cm. Therefore, each side is 42/3 = 14 cm.
Since an equilateral triangle has three congruent sides (and 3 congruent angles, each of 60⁰), the length of each side is 32/3 cm. If we draw one of the altitudes of the triangle, then a right triangle is formed where the side of a triangle is the hypotenuse, and the altitude is opposite to a 60 degrees angle. So we have, sin 60⁰ = altitude/(32/3 cm) (multiply by 32/3 cm to both sides) (32/3 cm)sin 60⁰ = altitude 9.2 cm = altitude
If the sides are different lengths it ain't equilateral...
This is not an equilateral triangle.
