Area of a triangle: To obtain the area of a triangle multiply the base by the height and then divide by 2.
Area (A) = 1/2(b × h) or b × h / 2
Thus, the height of the triangle h = Area × 2 / b
And, the base of triangle b = Area × 2 / h
Where h is denoted as height.
Where b is denoted as base.
The perimeter of a triangle: To obtain the perimeter of a triangle, add the lengths of each of its 3 sides.
Perimeter (P) = AB + BC + CA.
Perimeter (P) = a + b + c.
Where a, b, c is denoted as the length of three sides.
