## Does the perimeter of a triangle equal 180?

Explanation: The perimeter of the triangle is equal to the sum of the lengths of all the sides.

## What is the perimeter of ∆ ABC?

To find the perimeter of \triangle ABC we use the Pythagorean Theorem which tells us that |AB|^2 = |AC|^2 + |BC|^2. Since |AC| = 5 and |BC| = 12 we find that |AB| = \sqrt{169} = 13. The perimeter of \triangle ABC is then 5 + 12 + 13 = 30 units.

## How do you find a perimeter?

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides.

## How do you get the perimeter of a rectangle?

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

## How do you find the perimeter of two rectangles?

You are able to find the perimeter of the rectangle by adding length and width and multiplying by two because the opposite sides of a rectangle are equal in length. Both lengths of the rectangle are the same, and both widths are the same. For example, P = 2 * (14 + 8) = 2 * (22) = 44 centimeter (17.3 in).

## What is cuboid perimeter?

Perimeter of a cuboid = 4 (l + b + h)

## How do you find the perimeter of a rectangle if you know the area?

Perimeter of a Rectangle

1. Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)
2. Substitute the known values into the area formula. 36 = 4 * w. ...
3. Substitute values for length and width into the perimeter formula.

## What is the perimeter of 1 square foot?

12 inches

Since a square has all sides the same length, the perimeter (the distance around the outside of an object) is four times the side length (let's call this s). You know that the perimeter is 12 inches (one foot), so if we divide that by four, we get each side is length 3 inches.

## What is the perimeter of 20 square feet?
