Example Question #31 : How To Find The Perimeter Of A Triangle
What is the perimeter of an isosceles triangle with a base of and a side length of ?
Cannot determine
An isosceles triangle has a set of equal sides so the base is and the other two will be apiece.
The perimeter is all three sides added up so the perimeter will be
Example Question #31 : How To Find The Perimeter Of A Triangle
Find the perimeter of an equilateral triangle with a base of length 9 feet.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, we know the base of the triangle has a length of 9 feet. Because it is an equilateral triangle, we know that all sides are equal. This means that all sides are 9 feet. Knowing this, we can substitute into the formula. We get
Example Question #71 : Triangles
Find the perimeter of an equilateral triangle with a base of 4 feet.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, we know the base of the triangle is 4 feet. Because it is an equilateral triangle, we know that all sides are equal. Therefore, all sides are 4 feet. Knowing this, we can substitute into the formula. We get
Example Question #355 : Plane Geometry
Use the following equilateral triangle to answer the question:
Find the perimeter.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, let's look at the equilateral triangle.
We can see that one side has a length of 4ft. Because it is an equilateral triangle, all sides are equal. Therefore, all sides are 4ft.
Knowing this, we can substitute into the formula. We get
Example Question #72 : Triangles
Use the following triangle to solve the problem:
Find the perimeter.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, let's look at the triangle.
We can see the lengths of the sides are 9in, 3in, and 10in.
Knowing this, we can substitute into the formula. We get
Example Question #372 : Geometry
Use the following triangle to answer the question:
Find the perimeter.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, given the triangle
we can see the lengths of the sides are 11cm, 6cm, and 12cm.
Knowing this, we can substitute into the formula. We get
Example Question #81 : Triangles
Use the following triangle to answer the question:
Find the perimeter.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of the triangle.
Now, given the triangle
we can see it has sides of length 8ft, 4ft, and 7ft.
Knowing this, we can substitute into the formula. We get
Example Question #371 : Geometry
Find the perimeter of an equilateral triangle with a base of length 10cm.
To find the perimeter of a triangle, we will use the following formula:
where a, b, and c are the lengths of the sides of a triangle.
Now, we know the base of the triangle is 10cm. Because it is an equilateral triangle, all sides are equal. Therefore, all sides are 10cm.
Knowing this, we can substitute into the formula. We get
