# What is the relation between perimeter and area of a triangle?

Since the perimeter of any polygon is the sum of its side lengths, the perimeter of a triangle with side lengths a, b, and c is P = a + b + c. The formula for the area of a triangle can be derived either from the formula for the area of a rectangle or from the formula for the area of a parallelogram.

Also asked, how fo 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.

Additionally, what is the formula for perimeter of area? The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.

Furthermore, what is the area and perimeter of all shapes?

Perimeter is the distance around a two-dimensional shape such as square or rectangle or triangle. Area : The amount of space inside the boundary of a two- dimensional shape such as a triangle or circle.

What are the formulas for triangles?

Pythagoras' theorem states that in a right triangle (or right-angled triangle) the sum of the squares of the two smaller sides of the triangle is equal to the square of the hypotenuse.

• [ c = sqrt {a^2 + b^2} ]
• [ b = sqrt {c^2 - a^2} ]
• [ a = sqrt {c^2 - b^2} ]
