What is Area of a Triangle?

The area of a triangle is the amount of space enclosed between the sides of the triangle. The formula to find area of triangle is: 1/2 × base × height. It is calculated in square units.

Solved Example: 

Find the area of the triangle whose base is 4 units and height is 7 units.


To find the area of the triangle with base= 4 units and height= 7 units, we will use the above mentioned formula.

Area of triangle= (1/2 × base × height) square units

                         = 1/2 × 4 × 7 square units

                         = 14 square units

Therefore, the area of the given triangle is 14 square units.

Now, use the above area of triangle calculator to find the area of the triangles with following values of base and height:

  • Base= 6 units and height= 9 units
  • Base= 24 units and height= 22 units
