Answer: 24 inches.
Step-by-step explanation:
To find area of triangles, you can use the following formula:
[tex]A = (b*h)/2[/tex], where b is your base and h is your height.
You have the area and the height, so you can solve for the base:
[tex]408 = 34b/2[/tex]
Multiply both sides by 2:
[tex]816 = 34b[/tex]
Then, divide both sides by 34 to get your base.
