## How do you find perimeter with height?

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches.

## How do you find the perimeter of a triangle with base and height?

Calculate the Perimeter of a Right Triangle with Base as 3 cm and height as 4 cm. First, using the Pythagorean theorem, calculate the hypotenuse of the right triangle. So, the perimeter of the triangle = 3 + 4 + 5 = 12 cm.

**Can you find the perimeter of a triangle if you know the area?**

Take any triangle of sides a, b and c. The perimeter, P, is a+b+c. Let’s say the area of this triangle is A. Let x = P/A.

### How do you find the perimeter of a triangle with only the base?

The perimeter must be at least b+√b2+4h2, but can be made as large as you want, by putting the apex far away off to one side. If you know that both angles at the base are acute, then the perimeter must be less than b+h+√b2+h2.

### How do you find the perimeter of a triangle without one side?

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.

**What is the formula for perimeter of a triangle?**

Perimeter of a triangle formula. The formula for the perimeter of a triangle T is T = side a + side b + side c, as seen in the figure below: However, given different sets of other values about a triangle, it is possible to calculate the perimeter in other ways.

## How do you find the perimeter of a triangle?

Remember the formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c. What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.

## What is the perimeter of the triangle?

Perimeter of a Triangle. The perimeter of a triangle is the distance covered around the triangle and is calculated as the sum of all the three sides of it. The perimeter of a triangle = P = a + b + c units.

**What is the formula for perimeter?**

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height.
