The area of a triangle is given by the following formula:
[tex]A=\frac{bh}{2}[/tex]Since we are given the area and we need to find the height, we need to solve for "h". To do that we will first multiply by 2 on both sides:
[tex]2A=bh[/tex]Now we divide both sides by "b":
[tex]\frac{2A}{b}=h[/tex]Now we replace the known values:
[tex]\frac{2(16)}{4}=h[/tex]Solving the operations_
[tex]8=h[/tex]Therefore, the height is 8 ft
