Answer:

Step-by-step explanation:

recall the area of a triangle is  Area = 1/2* Base* height

then we know the height, and the area solve for the base

I'll do the algebra symbolically so you can see how

A = 1/2 *B * H  ( start here)

2A/H = B   ( move to here )    

Now plug in what you know on the left side

2*82.65/17.4 = base

9.5 = base  :)
