What is the perimeter in inches of the triangle?
To find the perimeter of a triangle — with sides a, b, and c — you add the lengths of the three sides. In this example, the lengths of the sides are 4 inches, 3 inches and 4 inches, respectively. You add 4 inches + 3 inches + 4 inches. This results in a perimeter of 11 inches.
How do you find the sides of a triangle when you know the perimeter?
Solution: Since all three sides are equal in length, the triangle is an equilateral triangle. Perimeter = 30 cm….Read More:

How do you find the perimeter of a triangle with two equal sides?
Since an isosceles triangle has two equal sides, its perimeter can be calculated if the base and the equal sides are known. The formula to calculate the perimeter of an isosceles triangle is P = 2a + b where ‘a’ is the length of the two equal sides and ‘b’ is the base of the triangle.
How do you convert area to perimeter of a triangle?
To find the perimeter of the square, add all four sides together. To find the area of a triangle, multiply together two of the sides (not the hypotenuse) and then multiply that figure by 1/2. To find the perimeter of the triangle, add all three sides together.
What is the formula for the perimeter of a triangle?
Perimeter of a triangle. The formula for the perimeter of a triangle is side a + side b + side c, but there are many rules through wihch one can calculate it.
What are the rules supported by the perimeter calculator?
Our perimeter calculator also supports the following rules: SAS (side, angle, side), SSA (side, side, angle), ASA (angle, side, angle) and the hypothenuse and side rule for right-angled triangles.
How do you find the perimeter of a set of angles?
Two sides and the angle between them (SAS) Use the law of cosines to find the third side and then the perimeter: perimeter = a + b + √(a² + b² – 2 * a * b * cos(γ))
What is the perimeter of a regular octagon?
The formula for the perimeter of a regular octagon is side x 8, as shown in the figure below: This is one of the easiest shapes to calculate the perimeter of – only a single measurement is required, and a simple multiplication by eight is all the calculation that needs to be done.
