#### Answer

16 ft

#### Work Step by Step

The area of a triangle can be found by using the formula A =1/2(b)(h).
b represents the length of the base of the triangle.
h represents the height of the triangle.
A represents the area of the triangle:
A is given as 32 ft, and h is given as 4 ft.
Plug these values into your formula, giving you:
32= $\frac{1}{2}$(b) $\times$4
Next, divide both sides by 4 leaving you with:
8=$\frac{1}{2}$(b)
After that, multiply by 2 to get ride of the coefficient in front of b leaving you with the answer:
b = 16 ft
