How To Find Perimeter Of Triangle?

What is the formula for finding 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.

Right Triangle
A triangle with one right angle. C = A + B = Pi/2 radians = 90o c2 = a2 + b2 (Pythagorean Theorem)
P = a + b + c s = (a+b+c)/2 K = ab/2 ha = b hb = a hc = ab/c ma = sqrt(4b2+a2)/2 mb = sqrt(4a2+b2)/2 mc = c/2

Perimeter of a Rectangle

  • 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)
  • Substitute the known values into the area formula. 36 = 4 * w.
  • Substitute values for length and width into the perimeter formula.
