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.

How do you find the area?
To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

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.
