The formula for the area of a triangle is A=1/2bh,where b is the base and h is the height of the triangle.The area of the triangular sail of the boat is 16ft2.The base is 12ft.What is the height of the sail.
A = (1/2)bh
16 = (1/2)(12)h simplify
16 = 6h divide both sides by 6
[16/6] ft = h = [ 8/3 ] ft = [2 + 2/3] ft
