Area of a triangle is calculated using the following formula:
multiply the base by the height then divide by two.

Area of a triangle

A = b × h ÷ 2

A = area
b = base of the triangle (see the images below)
h = height of the triangle (see the images below)

Area of a triangle

A right triangle is a triangle that has a right angle (90 degree angle). Its area is calculated using the same general formula.
