How do you find the area of a triangle
Anna007 [38]
Salutations!

How do you find the area of a triangle

To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:

hb/2 

H - height

B- Base

You need to multiply the base and height and divide it by 2.

Lets solve a question!

Find the area of a triangle with a base of 32mm and a height32 * 35 of 35mm

Area = hb/2

         = 32* 35

          = 1120

          = 1120/2

           = 56cm^2

Hope I helped (:

Have a great day!
