**Triangle**

**Introduction to triangle Area**

If we draw a diagonal of a rectangle then we get two equal sizes of triangles. So the area of these triangles will be half of the area of a rectangle.

The area of each triangle = 1/2 (Area of the rectangle)

Likewise, if we draw two diagonals of a square then we get four equal sizes of triangles .so the area of each triangle will be one-fourth of the area of the square.

The area of each triangle = 1/4 (Area of the square)

perimeter of triangle

To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be **P = a + b + c**.
