## Area of a Triangle

(figure available in print form)

Area of ABCD = AB x h

Area of ABC= 1/2 X AB x h

Area of a triangle = 1/2 x base x altitude

A = 1/2 bh

*
Example:
*

Find the area of a triangle whose base is 23.9 ft. and whose altitude is 14.8 ft.

*
Solution:
*

A =1/2 bh A-1/2 x 23.9 x 14.8 =1/2 x 353.72 =176.86 sq.ft.
