What is the perimeter of the given triangle?

Perimeter of a triangle = sum of all three sides If a, b and c are the sides of the triangle, then. Perimeter of triangle = a + b + c. Also, the unit of a triangle’s perimeter is the same as the units of the lengths of its sides.

How do you find the perimeter of a triangle with no sides given?

To find the perimeter of a triangle, use the formula perimeter = a + b + c, where a, b, and c are the lengths of the sides of the triangle.

How do you find the perimeter of a triangle with only 2 sides and an area?

To find the perimeter of a triangle, use the formula perimeter = a + b + c, where a, b, and c are the lengths of the sides of the triangle. For example, if the length of each side of the triangle is 5, you would just add 5 + 5 + 5 and get 15. Therefore, the perimeter of the triangle is 15.

How do you find the missing perimeter of a triangle?

Add up the lengths of the three side lengths to find the perimeter. Recall that the perimeter P = a + b + c. Now that you know the lengths of sides a, b and c, you simply need to add the lengths together to find the perimeter.

How do you find the perimeter of a triangle without the sides?

If it’s a right triangle, you can use the Pythagorean theorem (a2 + b2 = c2) to find the length of the missing side. From there, you can easily calculate the perimeter. For other types of triangles, you can use the law of cosines to find the perimeter if you know 2 sides and at least 1 of the angles.

How do you find the perimeter when one side is missing?

The length of one side is missing. To find the missing side length, write an addition sentence for the perimeter of the triangle. The perimeter of a triangle equals the sum of all of its side lengths. Add the lengths of the sides you know.

How do you find the perimeter of a square with the area?

Area of a Square = side × side = side² square units Perimeter = 4 x side = 4 √Area units. Thus, we can find the perimeter of a square given its area. Example: If area of square is 16 sq.cm.
