An equilateral triangle has a perimeter of  units. What is the length of each side?

Possible Answers:

 units

 units

 units

 units

Correct answer:

 units

Explanation:

Because an equilateral triangle has three sides that are the same length, divide the given perimeter by 3 to find the length of each side.

Example Question #61 : Properties Of Triangles

The perimeter of a equilateral triangle is . In meters, what is the length of a side of this triangle?

Possible Answers:

Correct answer:

Explanation:

Since all three sides are equal in an equilateral triangle, we can just divide the perimeter by 3 to find a side length.

Example Question #62 : Properties Of Triangles

The perimeter of an equilateral triangle is . What is the length of a side of this triangle?

Possible Answers:

Correct answer:

Explanation:

Because all the sides in an equilateral triangle are equal, we can just divide the perimeter by 3 to find the length of a side.

Example Question #63 : Properties Of Triangles

The perimeter of an equilateral triangle is . What is the length of one side of the triangle?

Possible Answers:

Correct answer:

Explanation:

Since an equilateral triangle has sides that are all the same, divide the perimeter by  to get the length of each side.

Example Question #64 : Properties Of Triangles

The perimeter of an equilateral triangle is 39 meters. In meters, how long is one side of the triangle?

Possible Answers:

Correct answer:

Explanation:

An equilateral triangle has sides that are the same length. Then, to find the length of one side, you only need to divide the perimeter by 3.

Example Question #65 : Properties Of Triangles

The perimeter of an equilateral triangle is . What is the length of one side of this triangle?

Possible Answers:

Correct answer:

Explanation:

Since an equilateral triangle has three equal sides, divide the perimeter by  to find the length of each side.

Example Question #2 : How To Find The Length Of The Side Of An Equilateral Triangle

The perimeter of an equilateral triangle is . What is the length of one side of this triangle?

Possible Answers:

Correct answer:

Explanation:

Since an equilateral triangle has three equal sides, divide the perimeter by  to find the length of one side.

Example Question #67 : Properties Of Triangles

What is the difference between an equilateral triangle and a scalene triangle? 

Possible Answers:

Their color 

The sum of their angle measurements

The number of side lengths 

The length of their sides

The sum of their side lengths 

Correct answer:

The length of their sides

Explanation:

Of the choices listed, the main difference between an equilateral triangle and a scalene triangle is their side lengths. An equilateral triangle has to have  equal sides, but a scalene triangle can have all different side lengths.
