Area of a Triangle: The area of triangle is the space bounded by its sides.
Formula for find out the area is as below,
Area = 1/2*base*height

Perimeter of a triangle: The perimeter of a triangle is the sum of the length of its sides.
Formula for find out the perimeter of a triangle is given below,
P = a+b+c

These are the basic concepts of triangle.
